+ * @author MCD Application Team\r
+ * @version V0.3.0\r
+ * @date 06-March-2015\r
+ * @brief RTC HAL module driver.\r
+ * This file provides firmware functions to manage the following \r
+ * functionalities of the Real Time Clock (RTC) peripheral:\r
+ * + Initialization and de-initialization functions\r
+ * + RTC Time and Date functions\r
+ * + RTC Alarm functions\r
+ * + Peripheral Control functions \r
+ * + Peripheral State functions\r
+ * \r
+ @verbatim\r
+ ==============================================================================\r
+ ##### Backup Domain Operating Condition #####\r
+ ==============================================================================\r
+ [..] The real-time clock (RTC), the RTC backup registers, and the backup \r
+ SRAM (BKP SRAM) can be powered from the VBAT voltage when the main \r
+ VDD supply is powered off.\r
+ To retain the content of the RTC backup registers, backup SRAM, and supply \r
+ the RTC when VDD is turned off, VBAT pin can be connected to an optional \r
+ standby voltage supplied by a battery or by another source.\r
+\r
+ [..] To allow the RTC operating even when the main digital supply (VDD) is turned\r
+ off, the VBAT pin powers the following blocks:\r
+ (#) The RTC\r
+ (#) The LSE oscillator\r
+ (#) The backup SRAM when the low power backup regulator is enabled\r
+ (#) PC13 to PC15 I/Os, plus PI8 I/O (when available)\r
+ \r
+ [..] When the backup domain is supplied by VDD (analog switch connected to VDD),\r
+ the following pins are available:\r
+ (#) PC14 and PC15 can be used as either GPIO or LSE pins\r
+ (#) PC13 can be used as a GPIO or as the RTC_AF1 pin\r
+ (#) PI8 can be used as a GPIO or as the RTC_AF2 pin\r
+ \r
+ [..] When the backup domain is supplied by VBAT (analog switch connected to VBAT \r
+ because VDD is not present), the following pins are available:\r
+ (#) PC14 and PC15 can be used as LSE pins only\r
+ (#) PC13 can be used as the RTC_AF1 pin \r
+ (#) PI8 can be used as the RTC_AF2 pin\r
+ (#) PC1 can be used as the RTC_AF3 pin\r
+ \r
+ ##### Backup Domain Reset #####\r
+ ==================================================================\r
+ [..] The backup domain reset sets all RTC registers and the RCC_BDCR register \r
+ to their reset values. The BKPSRAM is not affected by this reset. The only\r
+ way to reset the BKPSRAM is through the Flash interface by requesting \r
+ a protection level change from 1 to 0.\r
+ [..] A backup domain reset is generated when one of the following events occurs:\r
+ (#) Software reset, triggered by setting the BDRST bit in the \r
+ RCC Backup domain control register (RCC_BDCR). \r
+ (#) VDD or VBAT power on, if both supplies have previously been powered off. \r
+\r
+ ##### Backup Domain Access #####\r
+ ==================================================================\r
+ [..] After reset, the backup domain (RTC registers, RTC backup data \r
+ registers and backup SRAM) is protected against possible unwanted write \r
+ accesses. \r
+ [..] To enable access to the RTC Domain and RTC registers, proceed as follows:\r
+ (+) Enable the Power Controller (PWR) APB1 interface clock using the\r
+ __PWR_CLK_ENABLE() function.\r
+ (+) Enable access to RTC domain using the HAL_PWR_EnableBkUpAccess() function.\r
+ (+) Select the RTC clock source using the __HAL_RCC_RTC_CONFIG() function.\r
+ (+) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() function.\r
+ \r
+ \r
+ ##### How to use this driver #####\r
+ ==================================================================\r
+ [..] \r
+ (+) Enable the RTC domain access (see description in the section above).\r
+ (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour \r
+ format using the HAL_RTC_Init() function.\r
+ \r
+ *** Time and Date configuration ***\r
+ ===================================\r
+ [..] \r
+ (+) To configure the RTC Calendar (Time and Date) use the HAL_RTC_SetTime() \r
+ and HAL_RTC_SetDate() functions.\r
+ (+) To read the RTC Calendar, use the HAL_RTC_GetTime() and HAL_RTC_GetDate() functions. \r
+ \r
+ *** Alarm configuration ***\r
+ ===========================\r
+ [..]\r
+ (+) To configure the RTC Alarm use the HAL_RTC_SetAlarm() function. \r
+ You can also configure the RTC Alarm with interrupt mode using the HAL_RTC_SetAlarm_IT() function.\r
+ (+) To read the RTC Alarm, use the HAL_RTC_GetAlarm() function.\r
+ \r
+ ##### RTC and low power modes #####\r
+ ==================================================================\r
+ [..] The MCU can be woken up from a low power mode by an RTC alternate \r
+ function.\r
+ [..] The RTC alternate functions are the RTC alarms (Alarm A and Alarm B), \r
+ RTC wakeup, RTC tamper event detection and RTC time stamp event detection.\r
+ These RTC alternate functions can wake up the system from the Stop and \r
+ Standby low power modes.\r
+ [..] The system can also wake up from low power modes without depending \r
+ on an external interrupt (Auto-wakeup mode), by using the RTC alarm \r
+ or the RTC wakeup events.\r
+ [..] The RTC provides a programmable time base for waking up from the \r
+ Stop or Standby mode at regular intervals.\r
+ Wakeup from STOP and STANDBY modes is possible only when the RTC clock source\r
+ is LSE or LSI.\r

+ ##### Initialization and de-initialization functions #####\r
+ ===============================================================================\r
+ [..] This section provides functions allowing to initialize and configure the \r
+ RTC Prescaler (Synchronous and Asynchronous), RTC Hour format, disable \r
+ RTC registers Write protection, enter and exit the RTC initialization mode, \r
+ RTC registers synchronization check and reference clock detection enable.\r
+ (#) The RTC Prescaler is programmed to generate the RTC 1Hz time base. \r
+ It is split into 2 programmable prescalers to minimize power consumption.\r
+ (++) A 7-bit asynchronous prescaler and a 13-bit synchronous prescaler.\r
+ (++) When both prescalers are used, it is recommended to configure the \r
+ asynchronous prescaler to a high value to minimize power consumption.\r
+ (#) All RTC registers are Write protected. Writing to the RTC registers\r
+ is enabled by writing a key into the Write Protection register, RTC_WPR.\r
+ (#) To configure the RTC Calendar, user application should enter \r
+ initialization mode. In this mode, the calendar counter is stopped \r
+ and its value can be updated. When the initialization sequence is \r
+ complete, the calendar restarts counting after 4 RTCCLK cycles.\r
+ (#) To read the calendar through the shadow registers after Calendar \r
+ initialization, calendar update or after wakeup from low power modes \r
+ the software must first clear the RSF flag. The software must then \r
+ wait until it is set again before reading the calendar, which means \r
+ that the calendar registers have been correctly copied into the \r
+ RTC_TR and RTC_DR shadow registers.The HAL_RTC_WaitForSynchro() function \r
+ implements the above software sequence (RSF clear and RSF check).\r
