The PVD_IN (PB7) has to be configured in Analog mode + when PWR_PVDLevel_7 is selected (PLS[2:0] = 111). + + (+) A 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_PWR_PVD_EXTI_ENABLE_IT() macro. + (+) The PVD is stopped in Standby mode. + + *** WakeUp pin configuration *** + ================================ + [..] + (+) WakeUp pin is used to wake up the system from Standby mode. This pin is + forced in input pull-down configuration and is active on rising edges. + (+) There are two or three WakeUp pins: + WakeUp Pin 1 on PA.00. + WakeUp Pin 2 on PC.13. + WakeUp Pin 3 on PE.06. : Only on product with GPIOE available + + [..] + *** Main and Backup Regulators configuration *** + ================================================ + + (+) The main internal regulator can be configured to have a tradeoff between + performance and power consumption when the device does not operate at + the maximum frequency. This is done through __HAL_PWR_VOLTAGESCALING_CONFIG() + macro which configure VOS bit in PWR_CR register: + (++) When this bit is set (Regulator voltage output Scale 1 mode selected) + the System frequency can go up to 32 MHz. + (++) When this bit is reset (Regulator voltage output Scale 2 mode selected) + the System frequency can go up to 16 MHz. + (++) When this bit is reset (Regulator voltage output Scale 3 mode selected) + the System frequency can go up to 4.2 MHz. + + Refer to the datasheets for more details. + + *** Low Power modes configuration *** + ===================================== + [..] + The device features 5 low-power modes: + (+) Low power run mode: regulator in low power mode, limited clock frequency, + limited number of peripherals running. + (+) Sleep mode: Cortex-M3 core stopped, peripherals kept running. + (+) Low power sleep mode: Cortex-M3 core stopped, limited clock frequency, + limited number of peripherals running, regulator in low power mode. + (+) Stop mode: All clocks are stopped, regulator running, regulator in low power mode. + (+) Standby mode: VCORE domain powered off + + *** Low power run mode *** + ========================= + [..] + To further reduce the consumption when the system is in Run mode, the regulator can be + configured in low power mode. In this mode, the system frequency should not exceed + MSI frequency range1. + In Low power run mode, all I/O pins keep the same state as in Run mode. + + (+) Entry: + (++) VCORE in range2 + (++) Decrease the system frequency tonot exceed the frequency of MSI frequency range1. + (++) The regulator is forced in low power mode using the HAL_PWREx_EnableLowPowerRunMode() + function. + (+) Exit: + (++) The regulator is forced in Main regulator mode using the HAL_PWREx_DisableLowPowerRunMode() + function. + (++) Increase the system frequency if needed. + + *** Sleep mode *** + ================== + [..] + (+) Entry: + The Sleep mode is entered by using the HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFx) + functions with + (++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction + (++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction + + (+) Exit: + (++) Any peripheral interrupt acknowledged by the nested vectored interrupt + controller (NVIC) can wake up the device from Sleep mode. + + *** Low power sleep mode *** + ============================ + [..] + (+) Entry: + The Low power sleep mode is entered by using the HAL_PWR_EnterSLEEPMode(PWR_LOWPOWERREGULATOR_ON, PWR_SLEEPENTRY_WFx) + functions with + (++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction + (++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction + (+) The Flash memory can be switched off by using the control bits (SLEEP_PD in the FLASH_ACR register. + This reduces power consumption but increases the wake-up time. + + (+) Exit: + (++) If the WFI instruction was used to enter Low power sleep mode, any peripheral interrupt + acknowledged by the nested vectored interrupt controller (NVIC) can wake up the device + from Low power sleep mode. If the WFE instruction was used to enter Low power sleep mode, + the MCU exits Sleep mode as soon as an event occurs. + + *** Stop mode *** + ================= + [..] + The Stop mode is based on the Cortex-M3 deepsleep mode combined with peripheral + clock gating. The voltage regulator can be configured either in normal or low-power mode. + In Stop mode, all clocks in the VCORE domain are stopped, the PLL, the MSI, the HSI and + the HSE RC oscillators are disabled. Internal SRAM and register contents are preserved. + To get the lowest consumption in Stop mode, the internal Flash memory also enters low + power mode. When the Flash memory is in power-down mode, an additional startup delay is + incurred when waking up from Stop mode. + To minimize the consumption In Stop mode, VREFINT, the BOR, PVD, and temperature + sensor can be switched off before entering Stop mode. They can be switched on again by + software after exiting Stop mode using the ULP bit in the PWR_CR register. + In Stop mode, all I/O pins keep the same state as in Run mode. + + (+) Entry: + The Stop mode is entered using the HAL_PWR_EnterSTOPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFI ) + function with: + (++) Main regulator ON. + (++) Low Power regulator ON. + (++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction + (++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction + (+) Exit: + (++) By issuing an interrupt or a wakeup event, the MSI RC oscillator is selected as system clock. + + *** Standby mode *** + ==================== + [..] + The Standby mode allows to achieve the lowest power consumption.

Alarm functions + * + Peripheral Control functions + * + Peripheral State functions + * + @verbatim + =============================================================================== + ##### RTC Operating Condition ##### + =============================================================================== + [..] The real-time clock (RTC) and the RTC backup registers can be powered + from the VBAT voltage when the main VDD supply is powered off. + To retain the content of the RTC backup registers and supply the RTC + when VDD is turned off, VBAT pin can be connected to an optional + standby voltage supplied by a battery or by another source. + + [..] To allow the RTC operating even when the main digital supply (VDD) is turned + off, the VBAT pin powers the following blocks: + (#) The RTC + (#) The LSE oscillator + (#) PC13 to PC15 I/Os (when available) + + [..] When the backup domain is supplied by VDD (analog switch connected to VDD), + the following pins are available: + (#) PC14 and PC15 can be used as either GPIO or LSE pins + (#) PC13 can be used as a GPIO or as the RTC_AF1 pin + + [..] When the backup domain is supplied by VBAT (analog switch connected to VBAT + because VDD is not present), the following pins are available: + (#) PC14 and PC15 can be used as LSE pins only + (#) PC13 can be used as the RTC_AF1 pin + + ##### Backup Domain Reset ##### + =============================================================================== + [..] The backup domain reset sets all RTC registers and the RCC_BDCR register + to their reset values. + [..] A backup domain reset is generated when one of the following events occurs: + (#) Software reset, triggered by setting the BDRST bit in the + RCC Backup domain control register (RCC_BDCR). + (#) VDD or VBAT power on, if both supplies have previously been powered off. + + ##### Backup Domain Access ##### + =================================================================== + [..] After reset, the backup domain (RTC registers, RTC backup data + registers and backup SRAM) is protected against possible unwanted write + accesses. + [..] To enable access to the RTC Domain and RTC registers, proceed as follows: + (+) Enable the Power Controller (PWR) APB1 interface clock using the + __HAL_RCC_PWR_CLK_ENABLE() function. + (+) Enable access to RTC domain using the HAL_PWR_EnableBkUpAccess() function. + (+) Select the RTC clock source using the __HAL_RCC_RTC_CONFIG() function. + (+) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() function. + + + ##### How to use RTC Driver ##### + =================================================================== + [..] + (+) Enable the RTC domain access (see description in the section above). + (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour + format using the HAL_RTC_Init() function. + + *** Time and Date configuration *** + =================================== + [..] + (+) To configure the RTC Calendar (Time and Date) use the HAL_RTC_SetTime() + and HAL_RTC_SetDate() functions. + (+) To read the RTC Calendar, use the HAL_RTC_GetTime() and HAL_RTC_GetDate() functions. + + *** Alarm configuration *** + =========================== + [..] + (+) To configure the RTC Alarm use the HAL_RTC_SetAlarm() function. + You can also configure the RTC Alarm with interrupt mode using the + HAL_RTC_SetAlarm_IT() function. + (+) To read the RTC Alarm, use the HAL_RTC_GetAlarm() function. + + ##### RTC and low power modes ##### + ================================================================== + [..] The MCU can be woken up from a low power mode by an RTC alternate + function. + [..] The RTC alternate functions are the RTC alarms (Alarm A and Alarm B), + RTC wakeup, RTC tamper event detection and RTC time stamp event detection. + These RTC alternate functions can wake up the system from the Stop and + Standby low power modes. + [..] The system can also wake up from low power modes without depending + on an external interrupt (Auto-wakeup mode), by using the RTC alarm + or the RTC wakeup events. + [..] The RTC provides a programmable time base for waking up from the + Stop or Standby mode at regular intervals. + Wakeup from STOP and STANDBY modes is possible only when the RTC clock source + is LSE or LSI. + + *** Callback registration *** + ============================================= + + The compilation define USE_RTC_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + Use Function @ref HAL_RTC_RegisterCallback() to register an interrupt callback. + + Function @ref HAL_RTC_RegisterCallback() allows to register following callbacks: + (+) AlarmAEventCallback : RTC Alarm A Event callback. + (+) AlarmBEventCallback : RTC Alarm B Event callback. + (+) TimeStampEventCallback : RTC TimeStamp Event callback. + (+) WakeUpTimerEventCallback : RTC WakeUpTimer Event callback. + (+) Tamper1EventCallback : RTC Tamper 1 Event callback. + (+) Tamper2EventCallback : RTC Tamper 2 Event callback. + (+) Tamper3EventCallback : RTC Tamper 3 Event callback. + (+) MspInitCallback : RTC MspInit callback. + (+) MspDeInitCallback : RTC MspDeInit callback. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + Use function @ref HAL_RTC_UnRegisterCallback() to reset a callback to the default + weak function. + @ref HAL_RTC_UnRegisterCallback() takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) AlarmAEventCallback : RTC Alarm A Event callback. + (+) AlarmBEventCallback : RTC Alarm B Event callback. + (+) TimeStampEventCallback : RTC TimeStamp Event callback. + (+) WakeUpTimerEventCallback : RTC WakeUpTimer Event callback. + (+) Tamper1EventCallback : RTC Tamper 1 Event callback. + (+) Tamper2EventCallback : RTC Tamper 2 Event callback. + (+) Tamper3EventCallback : RTC Tamper 3 Event callback. + (+) MspInitCallback : RTC MspInit callback. + (+) MspDeInitCallback : RTC MspDeInit callback. + + By default, after the @ref HAL_RTC_Init() and when the state is HAL_RTC_STATE_RESET, + all callbacks are set to the corresponding weak functions : + examples @ref AlarmAEventCallback(), @ref WakeUpTimerEventCallback(). + Exception done for MspInit and MspDeInit callbacks that are reset to the legacy weak function + in the @ref HAL_RTC_Init()/@ref HAL_RTC_DeInit() only when these callbacks are null + (not registered beforehand). + If not, MspInit or MspDeInit are not null, @ref HAL_RTC_Init()/@ref HAL_RTC_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) + + Callbacks can be registered/unregistered in HAL_RTC_STATE_READY state only. + Exception done MspInit/MspDeInit that can be registered/unregistered + in HAL_RTC_STATE_READY or HAL_RTC_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 @ref HAL_RTC_RegisterCallback() before calling @ref HAL_RTC_DeInit() + or @ref HAL_RTC_Init() function. + + When The compilation define USE_HAL_RTC_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available and all callbacks + are set to the corresponding weak functions. + + @endverbatim + ****************************************************************************** + * @attention + * + *

* + Peripheral Control functions + * + Peripheral State functions + * + @verbatim + ============================================================================== + ##### How to use this driver ##### + ============================================================================== + [..] + The SPI HAL driver can be used as follows: + + (#) Declare a SPI_HandleTypeDef handle structure, for example: + SPI_HandleTypeDef hspi; + + (#)Initialize the SPI low level resources by implementing the HAL_SPI_MspInit() API: + (##) Enable the SPIx interface clock + (##) SPI pins configuration + (+++) Enable the clock for the SPI GPIOs + (+++) Configure these SPI pins as alternate function push-pull + (##) NVIC configuration if you need to use interrupt process + (+++) Configure the SPIx interrupt priority + (+++) Enable the NVIC SPI IRQ handle + (##) DMA Configuration if you need to use DMA process + (+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive Stream/Channel + (+++) Enable the DMAx clock + (+++) Configure the DMA handle parameters + (+++) Configure the DMA Tx or Rx Stream/Channel + (+++) Associate the initialized hdma_tx(or _rx) handle to the hspi DMA Tx or Rx handle + (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx or Rx Stream/Channel + + (#) Program the Mode, BidirectionalMode , Data size, Baudrate Prescaler, NSS + management, Clock polarity and phase, FirstBit and CRC configuration in the hspi Init structure. + + (#) Initialize the SPI registers by calling the HAL_SPI_Init() API: + (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc) + by calling the customized HAL_SPI_MspInit() API. + [..] + Circular mode restriction: + (#) The DMA circular mode cannot be used when the SPI is configured in these modes: + (##) Master 2Lines RxOnly + (##) Master 1Line Rx + (#) The CRC feature is not managed when the DMA circular mode is enabled + (#) When the SPI DMA Pause/Stop features are used, we must use the following APIs + the HAL_SPI_DMAPause()/ HAL_SPI_DMAStop() only under the SPI callbacks + [..] + Master Receive mode restriction: + (#) In Master unidirectional receive-only mode (MSTR =1, BIDIMODE=0, RXONLY=1) or + bidirectional receive mode (MSTR=1, BIDIMODE=1, BIDIOE=0), to ensure that the SPI + does not initiate a new transfer the following procedure has to be respected: + (##) HAL_SPI_DeInit() + (##) HAL_SPI_Init() + [..] + Callback registration: + + (#) The compilation flag USE_HAL_SPI_REGISTER_CALLBACKS when set to 1U + allows the user to configure dynamically the driver callbacks. + Use Functions HAL_SPI_RegisterCallback() to register an interrupt callback. + + Function HAL_SPI_RegisterCallback() allows to register following callbacks: + (++) TxCpltCallback : SPI Tx Completed callback + (++) RxCpltCallback : SPI Rx Completed callback + (++) TxRxCpltCallback : SPI TxRx Completed callback + (++) TxHalfCpltCallback : SPI Tx Half Completed callback + (++) RxHalfCpltCallback : SPI Rx Half Completed callback + (++) TxRxHalfCpltCallback : SPI TxRx Half Completed callback + (++) ErrorCallback : SPI Error callback + (++) AbortCpltCallback : SPI Abort callback + (++) MspInitCallback : SPI Msp Init callback + (++) MspDeInitCallback : SPI Msp DeInit callback + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + + (#) Use function HAL_SPI_UnRegisterCallback to reset a callback to the default + weak function. + HAL_SPI_UnRegisterCallback takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (++) TxCpltCallback : SPI Tx Completed callback + (++) RxCpltCallback : SPI Rx Completed callback + (++) TxRxCpltCallback : SPI TxRx Completed callback + (++) TxHalfCpltCallback : SPI Tx Half Completed callback + (++) RxHalfCpltCallback : SPI Rx Half Completed callback + (++) TxRxHalfCpltCallback : SPI TxRx Half Completed callback + (++) ErrorCallback : SPI Error callback + (++) AbortCpltCallback : SPI Abort callback + (++) MspInitCallback : SPI Msp Init callback + (++) MspDeInitCallback : SPI Msp DeInit callback + + [..] + By default, after the HAL_SPI_Init() and when the state is HAL_SPI_STATE_RESET + all callbacks are set to the corresponding weak functions: + examples HAL_SPI_MasterTxCpltCallback(), HAL_SPI_MasterRxCpltCallback(). + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak functions in the HAL_SPI_Init()/ HAL_SPI_DeInit() only when + these callbacks are null (not registered beforehand). + If MspInit or MspDeInit are not null, the HAL_SPI_Init()/ HAL_SPI_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state. + + [..] + Callbacks can be registered/unregistered in HAL_SPI_STATE_READY state only. + Exception done MspInit/MspDeInit functions that can be registered/unregistered + in HAL_SPI_STATE_READY or HAL_SPI_STATE_RESET state, + thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. + Then, the user first registers the MspInit/MspDeInit user callbacks + using HAL_SPI_RegisterCallback() before calling HAL_SPI_DeInit() + or HAL_SPI_Init() function. + + [..] + When the compilation define USE_HAL_PPP_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registering feature is not available + and weak (surcharged) callbacks are used. + + [..] + Using the HAL it is not possible to reach all supported SPI frequency with the different SPI Modes, + the following table resume the max SPI frequency reached with data size 8bits/16bits, + according to frequency of the APBx Peripheral Clock (fPCLK) used by the SPI instance. + + @endverbatim + + Additional table : + + DataSize = SPI_DATASIZE_8BIT: +
