##### How to use this driver #####
==============================================================================
[..]
The common HAL driver contains a set of generic and common APIs that can be
used by the PPP peripheral drivers and the user to start using the HAL.
[..]
The HAL contains two APIs' categories:
(+) Common HAL APIs
(+) Services HAL APIs

##### HAL Initialization and Configuration functions #####
===============================================================================
[..] This section provides functions allowing to:
(+) Initialize the Flash interface the NVIC allocation and initial time base
clock configuration.
(+) De-initialize common part of the HAL.
(+) Configure the time base source to have 1ms time base with a dedicated
Tick interrupt priority.
(++) SysTick timer is used by default as source of time base, but user
can eventually implement his proper time base source (a general purpose
timer for example or other time source), keeping in mind that Time base
duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
handled in milliseconds basis.
(++) Time base configuration function (HAL_InitTick ()) is called automatically
at the beginning of the program after reset by HAL_Init() or at any time
when clock is configured, by HAL_RCC_ClockConfig().
(++) Source of time base is configured to generate interrupts at regular
time intervals. Care must be taken if HAL_Delay() is called from a
peripheral ISR process, the Tick interrupt line must have higher priority
(numerically lower) than the peripheral interrupt. Otherwise the caller
ISR process will be blocked.
(++) functions affecting time base configurations are declared as __weak
to make override possible in case of other implementations in user file.

*** How to configure Systick using CORTEX HAL driver ***
========================================================
[..]
Setup SysTick Timer for time base.
(+) The HAL_SYSTICK_Config() function calls the SysTick_Config() function which
is a CMSIS function that:
(++) Configures the SysTick Reload register with value passed as function parameter.
(++) Configures the SysTick IRQ priority to the lowest value (0x03).
(++) Resets the SysTick Counter register.
(++) Configures the SysTick Counter clock source to be Core Clock Source (HCLK).
(++) Enables the SysTick Interrupt.
(++) Starts the SysTick Counter.
(+) You can change the SysTick Clock source to be HCLK_Div8 by calling the macro
__HAL_CORTEX_SYSTICKCLK_CONFIG(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the
HAL_SYSTICK_Config() function call. The __HAL_CORTEX_SYSTICKCLK_CONFIG() macro is defined
inside the stm32wbxx_hal_cortex.h file.
(+) You can change the SysTick IRQ priority by calling the
HAL_NVIC_SetPriority(SysTick_IRQn,...) function just after the HAL_SYSTICK_Config() function
call. The HAL_NVIC_SetPriority() call the NVIC_SetPriority() function which is a CMSIS function.
(+) To adjust the SysTick time base, use the following formula:
Reload Value = SysTick Counter Clock (Hz) x Desired Time base (s)
(++) Reload Value is the parameter to be passed for HAL_SYSTICK_Config() function
(++) Reload Value should not exceed 0xFFFFFF

##### How to use this driver #####
==============================================================================
[..]
The DMA Extension HAL driver can be used as follows:
(+) Configure the DMA_MUX Synchronization Block using HAL_DMAEx_ConfigMuxSync function.
(+) Configure the DMA_MUX Request Generator Block using HAL_DMAEx_ConfigMuxRequestGenerator function.
Functions HAL_DMAEx_EnableMuxRequestGenerator and HAL_DMAEx_DisableMuxRequestGenerator can then be used
to respectively enable/disable the request generator.
(+) To handle the DMAMUX Interrupts, the function HAL_DMAEx_MUX_IRQHandler should be called from
the DMAMUX IRQ handler i.e DMAMUX1_OVR_IRQHandler.
As only one interrupt line is available for all DMAMUX channels and request generators , HAL_DMAEx_MUX_IRQHandler should be
called with, as parameter, the appropriate DMA handle as many as used DMAs in the user project
(exception done if a given DMA is not using the DMAMUX SYNC block neither a request generator)

##### EXTI Peripheral features #####
==============================================================================
[..]
(+) Each Exti line can be configured within this driver.
(+) Exti line can be configured in 3 different modes
(++) Interrupt
(++) Event
(++) Both of them
(+) Configurable Exti lines can be configured with 3 different triggers
(++) Rising
(++) Falling
(++) Both of them
(+) When set in interrupt mode, configurable Exti lines have one
interrupt pending register:
(++) Trigger request occurred
(+) Exti lines 0 to 15 are linked to gpio pin number 0 to 15. Gpio port can
be selected through multiplexer.
##### How to use this driver #####
==============================================================================
[..]
(#) Configure the EXTI line using HAL_EXTI_SetConfigLine().
(++) Choose the interrupt line number by setting "Line" member from
EXTI_ConfigTypeDef structure.
(++) Configure the interrupt and/or event mode using "Mode" member from
EXTI_ConfigTypeDef structure.
(++) For configurable lines, configure rising and/or falling trigger
"Trigger" member from EXTI_ConfigTypeDef structure.
(++) For Exti lines linked to gpio, choose gpio port using "GPIOSel"
member from GPIO_InitTypeDef structure.
(#) Get current Exti configuration of a dedicated line using
HAL_EXTI_GetConfigLine().
(++) Provide exiting handle as parameter.
(++) Provide pointer on EXTI_ConfigTypeDef structure as second parameter.
(#) Clear Exti configuration of a dedicated line using HAL_EXTI_GetConfigLine().
(++) Provide exiting handle as parameter.
(#) Register callback to treat Exti interrupts using HAL_EXTI_RegisterCallback().
(++) Provide exiting handle as first parameter.
(++) Provide which callback will be registered using one value from
EXTI_CallbackIDTypeDef.
(++) Provide callback function pointer.
(#) Get interrupt pending bit using HAL_EXTI_GetPending().
(#) Clear interrupt pending bit using HAL_EXTI_GetPending().

[..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses
to the Flash memory. It implements the erase and program Flash memory operations
and the read and write protection mechanisms.
[..] The Flash memory interface accelerates code execution with a system of instruction
prefetch and cache lines.
[..] The FLASH main features are:
(+) Flash memory read operations
(+) Flash memory program/erase operations
(+) Program and Erase suspension
(+) Read / write protections (2 areas per features)
(+) CPU2 Security area
(+) Option bytes programming
(+) Prefetch on CPU1 I-Code and CPU2 S-bus
(+) 32 instruction cache lines of 4*64 bits on I-Code for CPU1
(+) 8 data cache lines of 4*64 bits on D-Code for CPU1
(+) 4 instruction cache lines of 1*64 bits on S-bus for CPU2
(+) 4 data cache lines of 1*64 bits on S-Bus for CPU2
(+) Error code correction (ECC) : Data in flash are 72-bits word
(8 bits added per double word)
##### How to use this driver #####
==============================================================================
[..]
This driver provides functions and macros to configure and program the FLASH
memory of all STM32WBxx devices.
(#) Flash Memory IO Programming functions:
(++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and
HAL_FLASH_Lock() functions
(++) Program functions: double word and fast program (full row programming)
(++) There are two modes of programming:
(+++) Polling mode using HAL_FLASH_Program() function
(+++) Interrupt mode using HAL_FLASH_Program_IT() function
(#) Interrupts and flags management functions:
(++) Handle FLASH interrupts by calling HAL_FLASH_IRQHandler()
(++) Callback functions are called when the flash operations are finished :
HAL_FLASH_EndOfOperationCallback() when everything is ok, otherwise
HAL_FLASH_OperationErrorCallback()
(++) Get error flag status by calling HAL_GetError()
(#) Option bytes management functions :
(++) Lock and Unlock the option bytes using HAL_FLASH_OB_Unlock() and
HAL_FLASH_OB_Lock() functions
(++) Launch the reload of the option bytes using HAL_FLASH_OB_Launch() function.
In this case, a reset is generated
[..]
In addition to these functions, this driver includes a set of macros allowing
to handle the following operations:
(+) Set the latency
(+) Enable/Disable the prefetch buffer
(+) Enable/Disable the suspend program or erase request
(+) Enable/Disable the Instruction cache and the Data cache
(+) Reset the Instruction cache and the Data cache
(+) Enable/Disable the Flash interrupts
(+) Monitor the Flash flags status

##### GPIO Peripheral features #####
==============================================================================
[..]
(+) Each port bit of the general-purpose I/O (GPIO) ports can be individually
configured by software in several modes:
(++) Input mode
(++) Analog mode
(++) Output mode
(++) Alternate function mode
(++) External interrupt/event lines
(+) During and just after reset, the alternate functions and external interrupt
lines are not active and the I/O ports are configured in input floating mode.
(+) All GPIO pins have weak internal pull-up and pull-down resistors, which can be
activated or not.
(+) In Output or Alternate mode, each IO can be configured on open-drain or push-pull
type and the IO speed can be selected depending on the VDD value.
(+) The microcontroller IO pins are connected to onboard peripherals/modules through a
multiplexer that allows only one peripheral alternate function (AF) connected
to an IO pin at a time. In this way, there can be no conflict between peripherals
sharing the same IO pin.
(+) All ports have external interrupt/event capability. To use external interrupt
lines, the port must be configured in input mode. All available GPIO pins are
connected to the 16 external interrupt/event lines from EXTI0 to EXTI15.
(+) The external interrupt/event controller consists of up to 28 edge detectors
(16 lines are connected to GPIO) for generating event/interrupt requests (each
input line can be independently configured to select the type (interrupt or event)
and the corresponding trigger event (rising or falling or both). Each line can
also be masked independently.
##### How to use this driver #####
==============================================================================
[..]
(#) Enable the GPIO AHB clock using the following function: __HAL_RCC_GPIOx_CLK_ENABLE().
(#) Configure the GPIO pin(s) using HAL_GPIO_Init().
(++) Configure the IO mode using "Mode" member from GPIO_InitTypeDef structure
(++) Activate Pull-up, Pull-down resistor using "Pull" member from GPIO_InitTypeDef
structure.
(++) In case of Output or alternate function mode selection: the speed is
configured through "Speed" member from GPIO_InitTypeDef structure.
(++) In alternate mode is selection, the alternate function connected to the IO
is configured through "Alternate" member from GPIO_InitTypeDef structure.
(++) Analog mode is required when a pin is to be used as ADC channel
or DAC output.
(++) In case of external interrupt/event selection the "Mode" member from
GPIO_InitTypeDef structure select the type (interrupt or event) and
the corresponding trigger event (rising or falling or both).
(#) In case of external interrupt/event mode selection, configure NVIC IRQ priority
mapped to the EXTI line using HAL_NVIC_SetPriority() and enable it using
HAL_NVIC_EnableIRQ().
(#) To get the level of a pin configured in input mode use HAL_GPIO_ReadPin().
(#) To set/reset the level of a pin configured in output mode use
HAL_GPIO_WritePin()/HAL_GPIO_TogglePin().
(#) To set the level of several pins and reset level of several other pins in
same cycle, use HAL_GPIO_WriteMultipleStatePin().
(#) To lock pin configuration until next reset use HAL_GPIO_LockPin().
(#) During and just after reset, the alternate functions are not
active and the GPIO pins are configured in input floating mode (except JTAG
pins).
(#) The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as general purpose
(PC14 and PC15, respectively) when the LSE oscillator is off. The LSE has
priority over the GPIO function.
(#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as
general purpose PH0 and PH1, respectively, when the HSE oscillator is off.
The HSE has priority over the GPIO function.

##### How to use this driver #####
==============================================================================
[..]
(#)Take a semaphore In 2-Step mode Using function HAL_HSEM_Take. This function takes as parameters :
(++) the semaphore ID from 0 to 31
(++) the process ID from 0 to 255
(#) Fast Take semaphore In 1-Step mode Using function HAL_HSEM_FastTake. This function takes as parameter :
(++) the semaphore ID from 0_ID to 31. Note that the process ID value is implicitly assumed as zero
(#) Check if a semaphore is Taken using function HAL_HSEM_IsSemTaken. This function takes as parameter :
(++) the semaphore ID from 0_ID to 31
(++) It returns 1 if the given semaphore is taken otherwise (Free) zero
(#)Release a semaphore using function with HAL_HSEM_Release. This function takes as parameters :
(++) the semaphore ID from 0 to 31
(++) the process ID from 0 to 255:
(++) Note: If ProcessID and MasterID match, semaphore is freed, and an interrupt
may be generated when enabled (notification activated). If ProcessID or MasterID does not match,
semaphore remains taken (locked)
(#)Release all semaphores at once taken by a given Master using function HAL_HSEM_Release_All
This function takes as parameters :
(++) the Release Key (value from 0 to 0xFFFF) can be Set or Get respectively by
HAL_HSEM_SetClearKey() or HAL_HSEM_GetClearKey functions
(++) the Master ID:
(++) Note: If the Key and MasterID match, all semaphores taken by the given CPU that corresponds
to MasterID will be freed, and an interrupt may be generated when enabled (notification activated). If the
Key or the MasterID doesn't match, semaphores remains taken (locked)
(#)Semaphores Release all key functions:
(++) HAL_HSEM_SetClearKey() to set semaphore release all Key
(++) HAL_HSEM_GetClearKey() to get release all Key
(#)Semaphores notification functions :
(++) HAL_HSEM_ActivateNotification to activate a notification callback on
a given semaphores Mask (bitfield). When one or more semaphores defined by the mask are released
the callback HAL_HSEM_FreeCallback will be asserted giving as parameters a mask of the released
semaphores (bitfield).
(++) HAL_HSEM_DeactivateNotification to deactivate the notification of a given semaphores Mask (bitfield).
(++) See the description of the macro __HAL_HSEM_SEMID_TO_MASK to check how to calculate a semaphore mask
Used by the notification functions
*** HSEM HAL driver macros list ***
=============================================
[..] Below the list of most used macros in HSEM HAL driver.
(+) __HAL_HSEM_SEMID_TO_MASK: Helper macro to convert a Semaphore ID to a Mask.
[..] Example of use :
[..] mask = __HAL_HSEM_SEMID_TO_MASK(8) | __HAL_HSEM_SEMID_TO_MASK(21) | __HAL_HSEM_SEMID_TO_MASK(25).
[..] All next macros take as parameter a semaphore Mask (bitfiled) that can be constructed using __HAL_HSEM_SEMID_TO_MASK as the above example.
(+) __HAL_HSEM_ENABLE_IT: Enable the specified semaphores Mask interrupts.
(+) __HAL_HSEM_DISABLE_IT: Disable the specified semaphores Mask interrupts.
(+) __HAL_HSEM_GET_IT: Checks whether the specified semaphore interrupt has occurred or not.
(+) __HAL_HSEM_GET_FLAG: Get the semaphores status release flags.
(+) __HAL_HSEM_CLEAR_FLAG: Clear the semaphores status release flags.

##### How to use this driver #####
==============================================================================
[..]
The IPCC HAL driver can be used as follows:
(#) Declare a IPCC_HandleTypeDef handle structure, for example: IPCC_HandleTypeDef hipcc;
(#) Initialize the IPCC low level resources by implementing the HAL_IPCC_MspInit() API:
(##) Enable the IPCC interface clock
(##) NVIC configuration if you need to use interrupt process
(+++) Configure the IPCC interrupt priority
(+++) Enable the NVIC IPCC IRQ
(#) Initialize the IPCC registers by calling the HAL_IPCC_Init() API which trig
HAL_IPCC_MspInit().
(#) Implement the interrupt callbacks for transmission and reception to use the driver in interrupt mode
(#) Associate those callback to the corresponding channel and direction using HAL_IPCC_ConfigChannel().
This is the interrupt mode.
If no callback are configured for a given channel and direction, it is up to the user to poll the
status of the communication (polling mode).
(#) Notify the other MCU when a message is available in a chosen channel
or when a message has been retrieved from a chosen channel by calling
the HAL_IPCC_NotifyCPU() API.

##### IO operation functions #####
===============================================================================
[..] This section provides functions to allow two MCU to communicate.
(#) For a given channel (from 0 to IPCC_CHANNEL_NUMBER), for a given direction
IPCC_CHANNEL_DIR_TX or IPCC_CHANNEL_DIR_RX, you can choose to communicate
in polling mode or in interrupt mode using IPCC.
By default, the IPCC HAL driver handle the communication in polling mode.
By setting a callback for a channel/direction, this communication use
the interrupt mode.
(#) Polling mode:
(++) To transmit information, use HAL_IPCC_NotifyCPU() with
IPCC_CHANNEL_DIR_TX. To know when the other processor has handled
the notification, poll the communication using HAL_IPCC_NotifyCPU
with IPCC_CHANNEL_DIR_TX.
(++) To receive information, poll the status of the communication with
HAL_IPCC_GetChannelStatus with IPCC_CHANNEL_DIR_RX. To notify the other
processor that the information has been received, use HAL_IPCC_NotifyCPU
with IPCC_CHANNEL_DIR_RX.
(#) Interrupt mode:
(++) Configure a callback for the channel and the direction using HAL_IPCC_ConfigChannel().
This callback will be triggered under interrupt.
(++) To transmit information, use HAL_IPCC_NotifyCPU() with
IPCC_CHANNEL_DIR_TX. The callback configured with HAL_IPCC_ConfigChannel() and
IPCC_CHANNEL_DIR_TX will be triggered once the communication has been handled by the
other processor.
(++) To receive information, the callback configured with HAL_IPCC_ConfigChannel() and
IPCC_CHANNEL_DIR_RX will be triggered on reception of a communication.To notify the other
processor that the information has been received, use HAL_IPCC_NotifyCPU
with IPCC_CHANNEL_DIR_RX.
(++) HAL_IPCC_TX_IRQHandler must be added to the IPCC TX IRQHandler

==============================================================================
##### IWDG Generic features #####
==============================================================================
[..]
(+) The IWDG can be started by either software or hardware (configurable
through option byte).
(+) The IWDG is clocked by the Low-Speed Internal clock (LSI) and thus stays
active even if the main clock fails.
(+) Once the IWDG is started, the LSI is forced ON and both cannot be
disabled. The counter starts counting down from the reset value (0xFFF).
When it reaches the end of count value (0x000) a reset signal is
generated (IWDG reset).
(+) Whenever the key value 0x0000 AAAA is written in the IWDG_KR register,
the IWDG_RLR value is reloaded into the counter and the watchdog reset
is prevented.
(+) The IWDG is implemented in the VDD voltage domain that is still functional
in STOP and STANDBY mode (IWDG reset can wake up the CPU from STANDBY).
IWDGRST flag in RCC_CSR register can be used to inform when an IWDG
reset occurs.
(+) Debug mode: When the microcontroller enters debug mode (core halted),
the IWDG counter either continues to work normally or stops, depending
on DBG_IWDG_STOP configuration bit in DBG module, accessible through
__HAL_DBGMCU_FREEZE_IWDG() and __HAL_DBGMCU_UNFREEZE_IWDG() macros.
[..] Min-max timeout value @32KHz (LSI): ~125us / ~32.7s
The IWDG timeout may vary due to LSI clock frequency dispersion.
STM32WBxx devices provide the capability to measure the LSI clock
frequency (LSI clock is internally connected to TIM16 CH1 input capture).
The measured value can be used to have an IWDG timeout with an
acceptable accuracy.
[..] Default timeout value (necessary for IWDG_SR status register update):
Constant LSI_VALUE is defined based on the nominal LSI clock frequency.
This frequency being subject to variations as mentioned above, the
default timeout value (defined through constant HAL_IWDG_DEFAULT_TIMEOUT
below) may become too short or too long.
In such cases, this default timeout value can be tuned by redefining
the constant LSI_VALUE at user-application level (based, for instance,
on the measured LSI clock frequency as explained above).
##### How to use this driver #####
==============================================================================
[..]
(#) Use IWDG using HAL_IWDG_Init() function to :
(++) Enable instance by writing Start keyword in IWDG_KEY register. LSI
clock is forced ON and IWDG counter starts counting down.
(++) Enable write access to configuration registers:
IWDG_PR, IWDG_RLR and IWDG_WINR.
(++) Configure the IWDG prescaler and counter reload value. This reload
value will be loaded in the IWDG counter each time the watchdog is
reloaded, then the IWDG will start counting down from this value.
(++) Depending on window parameter:
(+++) If Window Init parameter is same as Window register value,
nothing more is done but reload counter value in order to exit
function with exact time base.
(+++) Else modify Window register. This will automatically reload
watchdog counter.
(++) Wait for status flags to be reset.
(#) Then the application program must refresh the IWDG counter at regular
intervals during normal operation to prevent an MCU reset, using
HAL_IWDG_Refresh() function.
*** IWDG HAL driver macros list ***
====================================
[..]
Below the list of most used macros in IWDG HAL driver:
(+) __HAL_IWDG_START: Enable the IWDG peripheral
(+) __HAL_IWDG_RELOAD_COUNTER: Reloads IWDG counter with value defined in
the reload register

##### How to use this driver #####
==============================================================================
[..] The LCD HAL driver can be used as follows:
(#) Declare a LCD_HandleTypeDef handle structure.
-@- The frequency generator allows you to achieve various LCD frame rates
starting from an LCD input clock frequency (LCDCLK) which can vary
from 32 kHz up to 1 MHz.
(#) Initialize the LCD low level resources by implementing the HAL_LCD_MspInit() API:
(++) Enable the LCDCLK (same as RTCCLK): to configure the RTCCLK/LCDCLK, proceed as follows:
(+++) Use RCC function HAL_RCCEx_PeriphCLKConfig in indicating RCC_PERIPHCLK_LCD and
selected clock source (HSE, LSI or LSE)
(++) LCD pins configuration:
(+++) Enable the clock for the LCD GPIOs.
(+++) Configure these LCD pins as alternate function no-pull.
(++) Enable the LCD interface clock.
(#) Program the Prescaler, Divider, Blink mode, Blink Frequency Duty, Bias,
Voltage Source, Dead Time, Pulse On Duration, Contrast, High drive and Multiplexer
Segment in the Init structure of the LCD handle.
(#) Initialize the LCD registers by calling the HAL_LCD_Init() API.
-@- The HAL_LCD_Init() API configures also the low level Hardware GPIO, CLOCK, ...etc)
by calling the customized HAL_LCD_MspInit() API.
-@- After calling the HAL_LCD_Init() the LCD RAM memory is cleared
(#) Optionally you can update the LCD configuration using these macros:
(++) LCD High Drive using the __HAL_LCD_HIGHDRIVER_ENABLE() and __HAL_LCD_HIGHDRIVER_DISABLE() macros
(++) Voltage output buffer using __HAL_LCD_VOLTAGE_BUFFER_ENABLE() and __HAL_LCD_VOLTAGE_BUFFER_DISABLE() macros
(++) LCD Pulse ON Duration using the __HAL_LCD_PULSEONDURATION_CONFIG() macro
(++) LCD Dead Time using the __HAL_LCD_DEADTIME_CONFIG() macro
(++) The LCD Blink mode and frequency using the __HAL_LCD_BLINK_CONFIG() macro
(++) The LCD Contrast using the __HAL_LCD_CONTRAST_CONFIG() macro
(#) Write to the LCD RAM memory using the HAL_LCD_Write() API, this API can be called
more time to update the different LCD RAM registers before calling
HAL_LCD_UpdateDisplayRequest() API.
(#) The HAL_LCD_Clear() API can be used to clear the LCD RAM memory.
(#) When LCD RAM memory is updated enable the update display request using
the HAL_LCD_UpdateDisplayRequest() API.
[..] LCD and low power modes:
(#) The LCD remain active during Sleep, Low Power run, Low Power Sleep and
STOP modes.

##### IO operation functions #####
===============================================================================
[..] Using its double buffer memory the LCD controller ensures the coherency of the
displayed information without having to use interrupts to control LCD_RAM
modification.
[..] The application software can access the first buffer level (LCD_RAM) through
the APB interface. Once it has modified the LCD_RAM using the HAL_LCD_Write() API,
it sets the UDR flag in the LCD_SR register using the HAL_LCD_UpdateDisplayRequest() API.
[..] This UDR flag (update display request) requests the updated information to be
moved into the second buffer level (LCD_DISPLAY).
[..] This operation is done synchronously with the frame (at the beginning of the
next frame), until the update is completed, the LCD_RAM is write protected and
the UDR flag stays high.
[..] Once the update is completed another flag (UDD - Update Display Done) is set and
generates an interrupt if the UDDIE bit in the LCD_FCR register is set.
The time it takes to update LCD_DISPLAY is, in the worst case, one odd and one
even frame.
[..] The update will not occur (UDR = 1 and UDD = 0) until the display is
enabled (LCDEN = 1).

===============================================================================
##### Peripheral Control functions #####
===============================================================================
[..]
*** PVD configuration ***
=========================
[..]
(+) The PVD is used to monitor the VDD power supply by comparing it to a
threshold selected by the PVD Level (PLS[2:0] bits in PWR_CR2 register).
(+) PVDO flag is available to indicate if VDD/VDDA is higher or lower
than the PVD threshold. This event is internally connected to the EXTI
line16 and can generate an interrupt if enabled. This is done through
__HAL_PVD_EXTI_ENABLE_IT() macro.
(+) The PVD is stopped in Standby mode.
*** WakeUp pin configuration ***
================================
[..]
(+) WakeUp pins are used to wakeup the system from Standby mode or Shutdown mode.
The polarity of these pins can be set to configure event detection on high
level (rising edge) or low level (falling edge).
*** Low Power modes configuration ***
=====================================
[..]
The devices feature 8 low-power modes:
(+) Low-power Run mode: core and peripherals are running, main regulator off, low power regulator on.
(+) Sleep mode: Cortex-M4 core stopped, peripherals kept running, main and low power regulators on.
(+) Low-power Sleep mode: Cortex-M4 core stopped, peripherals kept running, main regulator off, low power regulator on.
(+) Stop 0 mode: all clocks are stopped except LSI and LSE, main and low power regulators on.
(+) Stop 1 mode: all clocks are stopped except LSI and LSE, main regulator off, low power regulator on.
(+) Stop 2 mode: all clocks are stopped except LSI and LSE, main regulator off, low power regulator on, reduced set of waking up IPs compared to Stop 1 mode.
(+) Standby mode with SRAM2a: all clocks are stopped except LSI and LSE, SRAM2a content preserved, main regulator off, low power regulator on.
Note: On devices STM32WB15xx, STM32WB10xx, STM32WB1Mxx retention is extended to SRAM1, SRAM2a, SRAM2b.
(+) Standby mode without SRAM2a: all clocks are stopped except LSI and LSE, main and low power regulators off.
(+) Shutdown mode: all clocks are stopped except LSE, main and low power regulators off.
*** Low-power run mode ***
==========================
[..]
(+) Entry: (from main run mode)
(++) set LPR bit with HAL_PWREx_EnableLowPowerRunMode() API after having decreased the system clock below 2 MHz.
(+) Exit:
(++) clear LPR bit then wait for REGLP bit to be reset with HAL_PWREx_DisableLowPowerRunMode() API. Only
then can the system clock frequency be increased above 2 MHz.
*** Sleep mode / Low-power sleep mode ***
=========================================
[..]
(+) Entry:
The Sleep mode / Low-power Sleep mode is entered thru HAL_PWR_EnterSLEEPMode() API
in specifying whether or not the regulator is forced to low-power mode and if exit is interrupt or event-triggered.
(++) PWR_MAINREGULATOR_ON: Sleep mode (regulator in main mode).
(++) PWR_LOWPOWERREGULATOR_ON: Low-power sleep (regulator in low power mode).
In the latter case, the system clock frequency must have been decreased below 2 MHz beforehand.
(++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction
(++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction
(+) WFI Exit:
(++) Any peripheral interrupt acknowledged by the nested vectored interrupt
controller (NVIC) or any wake-up event.
(+) WFE Exit:
(++) Any wake-up event such as an EXTI line configured in event mode.
[..] When exiting the Low-power sleep mode by issuing an interrupt or a wakeup event,
the MCU is in Low-power Run mode.
*** Stop 0, Stop 1 and Stop 2 modes ***
===============================
[..]
(+) Entry:
The Stop 0, Stop 1 or Stop 2 modes are entered thru the following API's:
(++) HAL_PWREx_EnterSTOP0Mode() for mode 0, HAL_PWREx_EnterSTOP1Mode() for mode 1, HAL_PWREx_EnterSTOP2Mode() for mode 2
or for porting reasons HAL_PWR_EnterSTOPMode().
Note: Low power Stop2 mode is not available on devices STM32WB15xx, STM32WB10xx, STM32WB1Mxx.
(+) Regulator setting (applicable to HAL_PWR_EnterSTOPMode() only):
(++) PWR_MAINREGULATOR_ON: Regulator in main mode (STOP0 mode)
(++) PWR_LOWPOWERREGULATOR_ON: Regulator in low-power mode (STOP1 mode)
(+) Exit (interrupt or event-triggered, specified when entering STOP mode):
(++) PWR_STOPENTRY_WFI: enter Stop mode with WFI instruction
(++) PWR_STOPENTRY_WFE: enter Stop mode with WFE instruction
(+) WFI Exit:
(++) Any EXTI Line (Internal or External) configured in Interrupt mode.
(++) Some specific communication peripherals (USART, LPUART, I2C) interrupts
when programmed in wakeup mode.
(+) WFE Exit:
(++) Any EXTI Line (Internal or External) configured in Event mode.
[..]
When exiting Stop 0 and Stop 1 modes, the MCU is either in Run mode or in Low-power Run mode
depending on the LPR bit setting.
When exiting Stop 2 mode, the MCU is in Run mode.
*** Standby mode ***
====================
[..] The Standby mode offers two options:
(+) option a) all clocks off except LSI and LSE, RRS bit set (keeps voltage regulator in low power mode).
SRAM and registers contents are lost except for the SRAM2 content, the RTC registers, RTC backup registers
and Standby circuitry.
(+) option b) all clocks off except LSI and LSE, RRS bit cleared (voltage regulator then disabled).
SRAM and register contents are lost except for the RTC registers, RTC backup registers
and Standby circuitry.
(++) Entry:
(+++) The Standby mode is entered thru HAL_PWR_EnterSTANDBYMode() API.
SRAM1 and register contents are lost except for registers in the Backup domain and
Standby circuitry. SRAM2 content can be preserved if the bit RRS is set in PWR_CR3 register.
To enable this feature, the user can resort to HAL_PWREx_EnableBKRAMContentRetention() API
to set RRS bit.
(++) Exit:
(+++) WKUP pin rising edge, RTC alarm or wakeup, tamper event, time-stamp event,
external reset in NRST pin, IWDG reset.
[..] After waking up from Standby mode, program execution restarts in the same way as after a Reset.
*** Shutdown mode ***
======================
[..]
In Shutdown mode,
voltage regulator is disabled, all clocks are off except LSE, RRS bit is cleared.
SRAM and registers contents are lost except for backup domain registers.
(+) Entry:
The Shutdown mode is entered thru HAL_PWREx_EnterSHUTDOWNMode() API.
(+) Exit:
(++) WKUP pin rising edge, RTC alarm or wakeup, tamper event, time-stamp event,
external reset in NRST pin.
[..] After waking up from Shutdown mode, program execution restarts in the same way as after a Reset.
*** Auto-wakeup (AWU) from low-power mode ***
=============================================
[..]
The MCU can be woken up from low-power mode by an RTC Alarm event, an RTC
Wakeup event, a tamper event or a time-stamp event, without depending on
an external interrupt (Auto-wakeup mode).
(+) RTC auto-wakeup (AWU) from the Stop, Standby and Shutdown modes
(++) To wake up from the Stop mode with an RTC alarm event, it is necessary to
configure the RTC to generate the RTC alarm using the HAL_RTC_SetAlarm_IT() function.
(++) To wake up from the Stop mode with an RTC Tamper or time stamp event, it
is necessary to configure the RTC to detect the tamper or time stamp event using the
HAL_RTCEx_SetTimeStamp_IT() or HAL_RTCEx_SetTamper_IT() functions.
(++) To wake up from the Stop mode with an RTC WakeUp event, it is necessary to
configure the RTC to generate the RTC WakeUp event using the HAL_RTCEx_SetWakeUpTimer_IT() function.

* @note All clocks in the VCORE domain are stopped; the PLL, the MSI,
* the HSI and the HSE oscillators are disabled. Some peripherals with the wakeup capability
* (I2Cx, USARTx and LPUART) can switch on the HSI to receive a frame, and switch off the HSI
* after receiving the frame if it is not a wakeup frame. In this case, the HSI clock is propagated

* The BOR is available.
* The voltage regulator can be configured either in normal (Stop 0) or low-power mode (Stop 1).
* @note When exiting Stop 0 or Stop 1 mode by issuing an interrupt or a wakeup event,
* the HSI RC oscillator is selected as system clock if STOPWUCK bit in RCC_CFGR register
* is set; the MSI oscillator is selected if STOPWUCK is cleared.
* @note When the voltage regulator operates in low power mode (Stop 1), an additional
* startup delay is incurred when waking up.
* By keeping the internal regulator ON during Stop mode (Stop 0), the consumption
* is higher although the startup time is reduced.
* @note Case of Stop0 mode with SMPS: Before entering Stop 0 mode with SMPS Step Down converter enabled,
* the HSI16 must be kept on by enabling HSI kernel clock (set HSIKERON register bit).

* @author MCD Application Team
* @brief RNG HAL module driver.
* This file provides firmware functions to manage the following
* functionalities of the Random Number Generator (RNG) peripheral:
* + Initialization and configuration functions
* + Peripheral Control functions
* + Peripheral State functions
*

@verbatim
==============================================================================
##### How to use this driver #####
==============================================================================
[..]
The RNG HAL driver can be used as follows:
(#) Enable the RNG controller clock using __HAL_RCC_RNG_CLK_ENABLE() macro
in HAL_RNG_MspInit().
(#) Activate the RNG peripheral using HAL_RNG_Init() function.
(#) Wait until the 32 bit Random Number Generator contains a valid
random data using (polling/interrupt) mode.
(#) Get the 32 bit random number using HAL_RNG_GenerateRandomNumber() function.
##### Callback registration #####
==================================
[..]
The compilation define USE_HAL_RNG_REGISTER_CALLBACKS when set to 1
allows the user to configure dynamically the driver callbacks.
[..]
Use Function HAL_RNG_RegisterCallback() to register a user callback.
Function HAL_RNG_RegisterCallback() allows to register following callbacks:
(+) ErrorCallback : RNG Error Callback.
(+) MspInitCallback : RNG MspInit.
(+) MspDeInitCallback : RNG MspDeInit.
This function takes as parameters the HAL peripheral handle, the Callback ID
and a pointer to the user callback function.
[..]
Use function HAL_RNG_UnRegisterCallback() to reset a callback to the default
weak (overridden) function.
HAL_RNG_UnRegisterCallback() takes as parameters the HAL peripheral handle,
and the Callback ID.
This function allows to reset following callbacks:
(+) ErrorCallback : RNG Error Callback.
(+) MspInitCallback : RNG MspInit.
(+) MspDeInitCallback : RNG MspDeInit.
[..]
For specific callback ReadyDataCallback, use dedicated register callbacks:
respectively HAL_RNG_RegisterReadyDataCallback() , HAL_RNG_UnRegisterReadyDataCallback().
[..]
By default, after the HAL_RNG_Init() and when the state is HAL_RNG_STATE_RESET
all callbacks are set to the corresponding weak (overridden) functions:
example HAL_RNG_ErrorCallback().
Exception done for MspInit and MspDeInit functions that are respectively
reset to the legacy weak (overridden) functions in the HAL_RNG_Init()
and HAL_RNG_DeInit() only when these callbacks are null (not registered beforehand).
If not, MspInit or MspDeInit are not null, the HAL_RNG_Init() and HAL_RNG_DeInit()
keep and use the user MspInit/MspDeInit callbacks (registered beforehand).
[..]
Callbacks can be registered/unregistered in HAL_RNG_STATE_READY state only.
Exception done MspInit/MspDeInit that can be registered/unregistered
in HAL_RNG_STATE_READY or HAL_RNG_STATE_RESET state, thus registered (user)
MspInit/DeInit callbacks can be used during the Init/DeInit.
In that case first register the MspInit/MspDeInit user callbacks
using HAL_RNG_RegisterCallback() before calling HAL_RNG_DeInit()
or HAL_RNG_Init() function.
[..]
When The compilation define USE_HAL_RNG_REGISTER_CALLBACKS is set to 0 or
not defined, the callback registration feature is not available
and weak (overridden) callbacks are used.

==============================================================================
##### WWDG Specific features #####
==============================================================================
[..]
Once enabled the WWDG generates a system reset on expiry of a programmed
time period, unless the program refreshes the counter (T[6;0] downcounter)
before reaching 0x3F value (i.e. a reset is generated when the counter
value rolls down from 0x40 to 0x3F).
(+) An MCU reset is also generated if the counter value is refreshed
before the counter has reached the refresh window value. This
implies that the counter must be refreshed in a limited window.
(+) Once enabled the WWDG cannot be disabled except by a system reset.
(+) If required by application, an Early Wakeup Interrupt can be triggered
in order to be warned before WWDG expiration. The Early Wakeup Interrupt
(EWI) can be used if specific safety operations or data logging must
be performed before the actual reset is generated. When the downcounter
reaches 0x40, interrupt occurs. This mechanism requires WWDG interrupt
line to be enabled in NVIC. Once enabled, EWI interrupt cannot be
disabled except by a system reset.
(+) WWDGRST flag in RCC CSR register can be used to inform when a WWDG
reset occurs.
(+) The WWDG counter input clock is derived from the APB clock divided
by a programmable prescaler.
(+) WWDG clock (Hz) = PCLK1 / (4096 * Prescaler)
(+) WWDG timeout (mS) = 1000 * (T[5;0] + 1) / WWDG clock (Hz)
where T[5;0] are the lowest 6 bits of Counter.
(+) WWDG Counter refresh is allowed between the following limits :
(++) min time (mS) = 1000 * (Counter - Window) / WWDG clock
(++) max time (mS) = 1000 * (Counter - 0x40) / WWDG clock
(+) Typical values:
(++) Counter min (T[5;0] = 0x00) at 64 MHz (PCLK1) with zero prescaler:
max timeout before reset: approximately 64us
(++) Counter max (T[5;0] = 0x3F) at 64 MHz (PCLK1) with prescaler
dividing by 128:
max timeout before reset: approximately 524.28ms
##### How to use this driver #####
==============================================================================
*** Common driver usage ***
===========================
[..]
(+) Enable WWDG APB1 clock using __HAL_RCC_WWDG_CLK_ENABLE().
(+) Configure the WWDG prescaler, refresh window value, counter value and early
interrupt status using HAL_WWDG_Init() function. This will automatically
enable WWDG and start its downcounter. Time reference can be taken from
function exit. Care must be taken to provide a counter value
greater than 0x40 to prevent generation of immediate reset.
(+) If the Early Wakeup Interrupt (EWI) feature is enabled, an interrupt is
generated when the counter reaches 0x40. When HAL_WWDG_IRQHandler is
triggered by the interrupt service routine, flag will be automatically
cleared and HAL_WWDG_WakeupCallback user callback will be executed. User
can add his own code by customization of callback HAL_WWDG_WakeupCallback.
(+) Then the application program must refresh the WWDG counter at regular
intervals during normal operation to prevent an MCU reset, using
HAL_WWDG_Refresh() function. This operation must occur only when
the counter is lower than the refresh window value already programmed.
*** Callback registration ***
=============================
[..]
The compilation define USE_HAL_WWDG_REGISTER_CALLBACKS when set to 1 allows
the user to configure dynamically the driver callbacks. Use Functions
HAL_WWDG_RegisterCallback() to register a user callback.
(+) Function HAL_WWDG_RegisterCallback() allows to register following
callbacks:
(++) EwiCallback : callback for Early WakeUp Interrupt.
(++) MspInitCallback : WWDG MspInit.
This function takes as parameters the HAL peripheral handle, the Callback ID
and a pointer to the user callback function.
(+) Use function HAL_WWDG_UnRegisterCallback() to reset a callback to
the default weak (surcharged) function. HAL_WWDG_UnRegisterCallback()
takes as parameters the HAL peripheral handle and the Callback ID.
This function allows to reset following callbacks:
(++) EwiCallback : callback for Early WakeUp Interrupt.
(++) MspInitCallback : WWDG MspInit.
[..]
When calling HAL_WWDG_Init function, callbacks are reset to the
corresponding legacy weak (surcharged) functions:
HAL_WWDG_EarlyWakeupCallback() and HAL_WWDG_MspInit() only if they have
not been registered before.
[..]
When compilation define USE_HAL_WWDG_REGISTER_CALLBACKS is set to 0 or
not defined, the callback registering feature is not available
and weak (surcharged) callbacks are used.
*** WWDG HAL driver macros list ***
===================================
[..]
Below the list of available macros in WWDG HAL driver.
(+) __HAL_WWDG_ENABLE: Enable the WWDG peripheral
(+) __HAL_WWDG_GET_FLAG: Get the selected WWDG's flag status
(+) __HAL_WWDG_CLEAR_FLAG: Clear the WWDG's pending flags
(+) __HAL_WWDG_ENABLE_IT: Enable the WWDG early wakeup interrupt
