+ ==============================================================================\r
+ ##### How to use this driver #####\r
+ ==============================================================================\r
+ [..] \r
+ (+) Enable the RTC domain access.\r
+ (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour \r
+ format using the HAL_RTC_Init() function.\r
+ \r
+ *** RTC Wakeup configuration ***\r
+ ================================\r
+ [..] \r
+ (+) To configure the RTC Wakeup Clock source and Counter use the HAL_RTC_SetWakeUpTimer()\r
+ function. You can also configure the RTC Wakeup timer in interrupt mode \r
+ using the HAL_RTC_SetWakeUpTimer_IT() function.\r
+ (+) To read the RTC WakeUp Counter register, use the HAL_RTC_GetWakeUpTimer() \r
+ function.\r
+ \r
+ *** TimeStamp configuration ***\r
+ ===============================\r
+ [..]\r
+ (+) Enables the RTC TimeStamp using the HAL_RTC_SetTimeStamp() function.\r
+ You can also configure the RTC TimeStamp with interrupt mode using the\r
+ HAL_RTC_SetTimeStamp_IT() function.\r
+ (+) To read the RTC TimeStamp Time and Date register, use the HAL_RTC_GetTimeStamp()\r
+ function.\r
+\r
+ *** Internal TimeStamp configuration ***\r
+ ===============================\r
+ [..]\r
+ (+) Enables the RTC internal TimeStamp using the HAL_RTC_SetInternalTimeStamp() function.\r
+ (+) To read the RTC TimeStamp Time and Date register, use the HAL_RTC_GetTimeStamp()\r
+ function.\r
+ \r
+ *** Tamper configuration ***\r
+ ============================\r
+ [..]\r
+ (+) Enable the RTC Tamper and Configure the Tamper filter count, trigger Edge \r
+ or Level according to the Tamper filter (if equal to 0 Edge else Level) \r
+ value, sampling frequency, NoErase, MaskFlag, precharge or discharge and\r
+ Pull-UP using the HAL_RTC_SetTamper() function. You can configure RTC Tamper\r
+ with interrupt mode using HAL_RTC_SetTamper_IT() function.\r
+ (+) The default configuration of the Tamper erases the backup registers. To avoid\r
+ erase, enable the NoErase field on the RTC_TAMPCR register.\r
+ \r
+ *** Backup Data Registers configuration ***\r
+ ===========================================\r
+ [..]\r
+ (+) To write to the RTC Backup Data registers, use the HAL_RTC_BKUPWrite()\r
+ function. \r
+ (+) To read the RTC Backup Data registers, use the HAL_RTC_BKUPRead()\r
+ function.\r
