+ ******************************************************************************
+ * @file stm32f0xx_hal_gpio.c
+ * @author MCD Application Team
+ * @version V1.0.0
+ * @date 20-May-2014
+ * @brief GPIO HAL module driver.
+ *
+ * This file provides firmware functions to manage the following
+ * functionalities of the General Purpose Input/Output (GPIO) peripheral:
+ * + Initialization/de-initialization function
+ * + IO operation function
+ *
+ @verbatim
+ ==============================================================================
+ ##### GPIO specific 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’s 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 23 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 : __GPIOx_CLK_ENABLE().
+
+ (#) In case of external interrupt/event mode selection, enable the SYSCFG clock
+ using the following function __SYSCFG_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,
+ the speed is configurable: 2 MHz, 10 MHz and 50 MHz.
+ (++) If alternate mode is selected, 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 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 PD0 and PD1, respectively, when the HSE oscillator is off.
+ The HSE has priority over the GPIO function.

+ * + Initialization and de-initialization functions
+ * + IO operation functions
+ * + Peripheral State functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ The I2C HAL driver can be used as follows:
+
+ (#) Declare a I2C_HandleTypeDef handle structure, for example:
+ I2C_HandleTypeDef hi2c;
+
+ (#)Initialize the I2C low level resources by implement the HAL_I2C_MspInit ()API:
+ (##) Enable the I2Cx interface clock
+ (##) I2C pins configuration
+ (+++) Enable the clock for the I2C GPIOs
+ (+++) Configure I2C pins as alternate function open-drain
+ (##) NVIC configuration if you need to use interrupt process
+ (+++) Configure the I2Cx interrupt priority
+ (+++) Enable the NVIC I2C IRQ Channel
+ (##) DMA Configuration if you need to use DMA process
+ (+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive stream
+ (+++) Enable the DMAx interface clock using
+ (+++) Configure the DMA handle parameters
+ (+++) Configure the DMA Tx or Rx Stream
+ (+++) Associate the initilalized DMA handle to the hi2c DMA Tx or Rx handle
+ (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx or Rx Stream
+
+ (#) Configure the Communication Clock Timing, Own Address1, Master Adressing Mode, Dual Addressing mode,
+ Own Address2, Own Address2 Mask, General call and Nostretch mode in the hi2c Init structure.
+
+ (#) Initialize the I2C registers by calling the HAL_I2C_Init() API:
+ (+++) These API's configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
+ by calling the customed HAL_I2C_MspInit(&hi2c) API.
+
+ (#) To check if target device is ready for communication, use the function HAL_I2C_IsDeviceReady()
+
+ (#) For I2C IO and IO MEM operations, three mode of operations are available within this driver :
+
+ *** Polling mode IO operation ***
+ =================================
+ [..]
+ (+) Transmit in master mode an amount of data in blocking mode using HAL_I2C_Master_Transmit()
+ (+) Receive in master mode an amount of data in blocking mode using HAL_I2C_Master_Receive()
+ (+) Transmit in slave mode an amount of data in blocking mode using HAL_I2C_Slave_Transmit()
+ (+) Receive in slave mode an amount of data in blocking mode using HAL_I2C_Slave_Receive()
+
+ *** Polling mode IO MEM operation ***
+ =====================================
+ [..]
+ (+) Write an amount of data in blocking mode to a specific memory address using HAL_I2C_Mem_Write()
+ (+) Read an amount of data in blocking mode from a specific memory address using HAL_I2C_Mem_Read()
+
+
+ *** Interrupt mode IO operation ***
+ ===================================
+ [..]
+ (+) Transmit in master mode an amount of data in non blocking mode using HAL_I2C_Master_Transmit_IT()
+ (+) At transmission end of transfer HAL_I2C_MasterTxCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_I2C_MasterTxCpltCallback
+ (+) Receive in master mode an amount of data in non blocking mode using HAL_I2C_Master_Receive_IT()

+* @brief I2S HAL module driver.
+*
+* This file provides firmware functions to manage the following
+* functionalities of the Integrated Interchip Sound (I2S) peripheral:
+* + Initialization and de-initialization functions
+* + IO operation functions
+* + Peripheral State and Errors functions
+@verbatim
+===============================================================================
+##### How to use this driver #####
+===============================================================================
+[..]
+The I2S HAL driver can be used as follows:
+
+(#) Declare a I2S_HandleTypeDef handle structure.
+(#) Initialize the I2S low level resources by implement the HAL_I2S_MspInit() API:
+(##) Enable the SPIx interface clock.
+(##) I2S pins configuration:
+(+++) Enable the clock for the I2S GPIOs.
+(+++) Configure these I2S pins as alternate function pull-up.
+(##) NVIC configuration if you need to use interrupt process (HAL_I2S_Transmit_IT()
+and HAL_I2S_Receive_IT() APIs).
+(+++) Configure the I2Sx interrupt priority.
+(+++) Enable the NVIC I2S IRQ handle.
+(##) DMA Configuration if you need to use DMA process (HAL_I2S_Transmit_DMA()
+and HAL_I2S_Receive_DMA() APIs:
+(+++) Declare a DMA handle structure for the Tx/Rx stream.
+(+++) Enable the DMAx interface clock.
+(+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
+(+++) Configure the DMA Tx/Rx Channel.
+(+++) Associate the initilalized DMA handle to the I2S DMA Tx/Rx handle.
+(+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the
+DMA Tx/Rx Channel.
+
+(#) Program the Mode, Standard, Data Format, MCLK Output, Audio frequency and Polarity
+using HAL_I2S_Init() function.
+
+-@- The specific I2S interrupts (Transmission complete interrupt,
+RXNE interrupt and Error Interrupts) will be managed using the macros
+__I2S_ENABLE_IT() and __I2S_DISABLE_IT() inside the transmit and receive process.
+-@- Make sure that either:
+(+@) External clock source is configured after setting correctly
+the define constant EXTERNAL_CLOCK_VALUE in the stm32f0xx_hal_conf.h file.
+
+(#) Three mode of operations are available within this driver :
+
+*** Polling mode IO operation ***
+=================================
+[..]
+(+) Send an amount of data in blocking mode using HAL_I2S_Transmit()
+(+) Receive an amount of data in blocking mode using HAL_I2S_Receive()
+
+*** Interrupt mode IO operation ***
+===================================
+[..]
+(+) Send an amount of data in non blocking mode using HAL_I2S_Transmit_IT()
+(+) At transmission end of half transfer HAL_I2S_TxHalfCpltCallback is executed and user can
+add his own code by customization of function pointer HAL_I2S_TxHalfCpltCallback
+(+) At transmission end of transfer HAL_I2S_TxCpltCallback is executed and user can
+add his own code by customization of function pointer HAL_I2S_TxCpltCallback
+(+) Receive an amount of data in non blocking mode using HAL_I2S_Receive_IT()
+(+) At reception end of half transfer HAL_I2S_RxHalfCpltCallback is executed and user can
+add his own code by customization of function pointer HAL_I2S_RxHalfCpltCallback
+(+) At reception end of transfer HAL_I2S_RxCpltCallback is executed and user can

+ * @brief IRDA HAL module driver.
+ *
+ * This file provides firmware functions to manage the following

+ * (IRDA)
+ * + Initialization and de-initialization function
+ * + IO operation function
+ * + Peripheral Control function
+ *
+ *
+ @verbatim
+ ===============================================================================
+ ##### How to use this driver #####
+ ===============================================================================
+ [..]
+ The IRDA HAL driver can be used as follows:
+
+ (#) Declare a IRDA_HandleTypeDef handle structure.
+ (#) Initialize the IRDA low level resources by implementing the HAL_IRDA_MspInit() API
+ in setting the associated USART or UART in IRDA mode:
+ (##) Enable the USARTx/UARTx interface clock.
+ (##) USARTx/UARTx pins configuration:
+ (+) Enable the clock for the USARTx/UARTx GPIOs.
+ (+) Configure these USARTx/UARTx pins as alternate function pull-up.
+ (##) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
+ and HAL_IRDA_Receive_IT() APIs):
+ (+) Configure the USARTx/UARTx interrupt priority.
+ (+) Enable the NVIC IRDA IRQ handle.
+ (@) The specific IRDA interrupts (Transmission complete interrupt,
+ RXNE interrupt and Error Interrupts) will be managed using the macros
+ __HAL_IRDA_ENABLE_IT() and __HAL_IRDA_DISABLE_IT() inside the transmit and receive process.
+ (##) DMA Configuration if you need to use DMA process (HAL_IRDA_Transmit_DMA()
+ and HAL_IRDA_Receive_DMA() APIs):
+ (+) Declare a DMA handle structure for the Tx/Rx stream.
+ (+) Enable the DMAx interface clock.
+ (+) Configure the declared DMA handle structure with the required Tx/Rx parameters.
+ (+) Configure the DMA Tx/Rx Stream.
+ (+) Associate the initilalized DMA handle to the IRDA DMA Tx/Rx handle.
+ (+) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
+
+ (#) Program the Baud Rate, Word Length and Parity and Mode(Receiver/Transmitter),
+ the normal or low power mode and the clock prescaler in the hirda Init structure.
+
+ (#) Initialize the IRDA registers by calling
+ the HAL_IRDA_Init() API.
+
+ (@) This API (HAL_IRDA_Init()) configures also the low level Hardware (GPIO, CLOCK, CORTEX...etc)
+ by calling the customized HAL_IRDA_MspInit() API.

+ [..]
+ This subsection provides a set of functions allowing to initialize the USARTx
+ in asynchronous IRDA mode.
+ (+) For the asynchronous mode only these parameters can be configured:
+ (++) Baud Rate
+ (++) Word Length
+ (++) Parity: If the parity is enabled, then the MSB bit of the data written
+ in the data register is transmitted but is changed by the parity bit.
+ Depending on the frame length defined by the M bit (8-bits or 9-bits)
+ or by the M1 and M0 bits (7-bit, 8-bit or 9-bit),
+ the possible IRDA frame formats are as listed in the following table:
+ +---------------------------------------------------------------+
+ | M bit | PCE bit | IRDA frame |
+ |-----------|-----------|---------------------------------------|
+ | 0 | 0 | | SB | 8-bit data | STB | |
+ |-----------|-----------|---------------------------------------|
+ | 0 | 1 | | SB | 7-bit data | PB | STB | |

+ ##### I/O operation functions #####
+ ===============================================================================
+ This subsection provides a set of functions allowing to manage the IRDA asynchronous
+ data transfers.
+
+ (#) There are two modes of transfer:
+ (+) Blocking mode: the communication is performed in polling mode.
+ The HAL status of all data processing is returned by the same function
+ after finishing transfer.
+ (+) No-Blocking mode: the communication is performed using Interrupts
+ or DMA, these API's return the HAL status.
+ The end of the data processing will be indicated through the
+ dedicated IRDA IRQ when using Interrupt mode or the DMA IRQ when
+ using DMA mode.
+ The HAL_IRDA_TxCpltCallback(), HAL_IRDA_RxCpltCallback() user callbacks
+ will be executed respectivelly at the end of the Transmit or Receive process
+ The HAL_IRDA_ErrorCallback() user callback will be executed when a communication error is detected
+
+ (#) Blocking mode API's are :
+ (+) HAL_IRDA_Transmit()
+ (+) HAL_IRDA_Receive()
+
+ (#) Non-Blocking mode API's with Interrupt are :
+ (+) HAL_IRDA_Transmit_IT()
+ (+) HAL_IRDA_Receive_IT()
+ (+) HAL_IRDA_IRQHandler()
+ (+) IRDA_Transmit_IT()
+ (+) IRDA_Receive_IT()
+
+ (#) Non-Blocking mode functions with DMA are :
+ (+) HAL_IRDA_Transmit_DMA()
+ (+) HAL_IRDA_Receive_DMA()
+
+ (#) A set of Transfer Complete Callbacks are provided in No_Blocking mode:
+ (+) HAL_IRDA_TxCpltCallback()

+ * @brief IWDG HAL module driver.
+ *
+ * This file provides firmware functions to manage the following
+ * functionalities of the IWDG peripheral:
+ * + Initialization and Configuration functions
+ * + IO operation functions
+ * + Peripheral State functions
+ *
+ @verbatim
+
+================================================================================
+ ##### IWDG specific features #####
+================================================================================
+ [..]
+ (+) The IWDG can be started by either software or hardware (configurable
+ through option byte).
+ (+) The IWDG is clocked by its own dedicated Low-Speed clock (LSI) and
+ thus stays active even if the main clock fails.
+ (+) Once the IWDG is started, the LSI is forced ON and cannot be disabled
+ (LSI cannot be disabled too), and the counter starts counting down from
+ the reset value of 0xFFF. When it reaches the end of count value (0x000)
+ a system reset is generated.
+ (+) The IWDG counter should be refreshed at regular intervals, otherwise the
+ watchdog generates an MCU reset when the counter reaches 0.
+ (+) The IWDG is implemented in the VDD voltage domain that is still functional
+ in STOP and STANDBY mode (IWDG reset can wake-up from STANDBY).
+ (+) IWDGRST flag in RCC_CSR register can be used to inform when an IWDG
+ reset occurs.
+ (+) Min-max timeout value @41KHz (LSI): ~0.1ms / ~25.5s
+ The IWDG timeout may vary due to LSI frequency dispersion. STM32F0x
+ devices provide the capability to measure the LSI frequency (LSI clock
+ connected internally to TIM16 CH1 input capture). The measured value
+ can be used to have an IWDG timeout with an acceptable accuracy.
+ For more information, please refer to the STM32F0x Reference manual.
+
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ (#) if Window option is disabled
+ (+) Use IWDG using HAL_IWDG_Init() function to :
+ (++) Enable write access to IWDG_PR, IWDG_RLR.
+ (++) Configure the IWDG prescaler, counter reload value.
+ This reload value will be loaded in the IWDG counter each time the counter
+ is reloaded, then the IWDG will start counting down from this value.
+ (+) Use IWDG using HAL_IWDG_Start() function to :
+ (++) Reload IWDG counter with value defined in the IWDG_RLR register.
+ (++) Start the IWDG, when the IWDG is used in software mode (no need
+ to enable the LSI, it will be enabled by hardware).
+ (+) 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.
+ (#) if Window option is enabled:
+ (+) Use IWDG using HAL_IWDG_Start() function to enable IWDG downcounter
+ (+) Use IWDG using HAL_IWDG_Init() function to :
+ (++) Enable write access to IWDG_PR, IWDG_RLR and IWDG_WINR registers.
+ (++) Configure the IWDG prescaler, reload value and window value.
+ (+) 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
+ (+) __HAL_IWDG_ENABLE_WRITE_ACCESS : Enable write access to IWDG_PR and IWDG_RLR registers
+ (+) __HAL_IWDG_DISABLE_WRITE_ACCESS : Disable write access to IWDG_PR and IWDG_RLR registers
+ (+) __HAL_IWDG_GET_FLAG: Get the selected IWDG's flag status

+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ The PCD HAL driver can be used as follows:
+
+ (#) Declare a PCD_HandleTypeDef handle structure, for example:
+ PCD_HandleTypeDef hpcd;
+
+ (#) Fill parameters of Init structure in HCD handle
+
+ (#) Call HAL_PCD_Init() API to initialize the HCD peripheral (Core, Device core, ...)
+
+ (#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API:
+ (##) Enable the PCD/USB Low Level interface clock using
+ (+++) __USB_CLK_ENABLE);
+
+ (##) Initialize the related GPIO clocks
+ (##) Configure PCD pin-out
+ (##) Configure PCD NVIC interrupt
+
+ (#)Associate the Upper USB device stack to the HAL PCD Driver:
+ (##) hpcd.pData = pdev;
+
+ (#)Enable HCD transmission and reception:
+ (##) HAL_PCD_Start();

+
+ *** WakeUp pin configuration ***
+ ================================
+ [..]
+ (+) WakeUp pin is used to wakeup the system from Standby mode. This pin is
+ forced in input pull down configuration and is active on rising edges.
+ (+) There are two WakeUp pins, and up to eight Wakeup pins on STM32F07x devices.
+ WakeUp Pin 1 on PA.00.
+ WakeUp Pin 2 on PC.13.
+ WakeUp Pin 3 on PE.06.(STM32F07x)
+ WakeUp Pin 4 on PA.02.(STM32F07x)
+ WakeUp Pin 5 on PC.05.(STM32F07x)
+ WakeUp Pin 6 on PB.05.(STM32F07x)
+ WakeUp Pin 7 on PB.15.(STM32F07x)
+ WakeUp Pin 8 on PF.02.(STM32F07x)
+
+ *** Low Power modes configuration ***
+ =====================================
+ [..]
+ The devices feature 3 low-power modes:
+ (+) Sleep mode: Cortex-M0 core stopped, peripherals kept running.
+ (+) Stop mode: All clocks are stopped, regulator running, regulator
+ in low power mode
+ (+) Standby mode: 1.8V domain powered off
+ Note: Standby mode is not available on STM32F0x8 devices.
+
+ *** 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.
+
+ *** Stop mode ***
+ =================
+ [..]
+ In Stop mode, all clocks in the 1.8V domain are stopped, the PLL, the HSI,
+ and the HSE RC oscillators are disabled. Internal SRAM and register contents
+ are preserved.
+ The voltage regulator can be configured either in normal or low-power mode.
+ To minimize the consumption.
+
+ (+) Entry:
+ The Stop mode is entered using the HAL_PWR_EnterSTOPMode(PWR_MAINREGULATOR_ON, PWR_STOPENTRY_WFI )
+ function with:
+ (++) Main regulator ON.
+ (++) Low Power regulator ON.
+ (++) PWR_STOPENTRY_WFI: enter STOP mode with WFI instruction
+ (++) PWR_STOPENTRY_WFE: enter STOP mode with WFE instruction
+ (+) Exit:
+ (++) Any EXTI Line (Internal or External) configured in Interrupt/Event mode.
+ (++) Some specific communication peripherals (CEC, USART, I2C) interrupts,
+ when programmed in wakeup mode (the peripheral must be
+ programmed in wakeup mode and the corresponding interrupt vector
+ must be enabled in the NVIC)
+
+ *** Standby mode ***
+ ====================
+ [..]
+ The Standby mode allows to achieve the lowest power consumption. It is based
+ on the Cortex-M0 deep sleep mode, with the voltage regulator disabled.
+ The 1.8V domain is consequently powered off. The PLL, the HSI oscillator and
+ the HSE oscillator are also switched off. SRAM and register contents are lost
+ except for the RTC registers, RTC backup registers and Standby
+ circuitry.
+ The voltage regulator is OFF.
+
+ (+) Entry:
+ (++) The Standby mode is entered using the HAL_PWR_EnterSTANDBYMode() function.
+ (+) Exit:
+ (++) WKUP pin rising edge, RTC alarm (Alarm A), RTC wakeup,
+ tamper event, time-stamp event, external reset in NRST pin, IWDG 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 and Standby 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_RTC_SetTimeStamp_IT() or HAL_RTC_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_RTC_SetWakeUpTimer_IT() function.
