<> 144:ef7eb2e8f9f7 17 ===================================================================
<> 144:ef7eb2e8f9f7 18 [..]
<> 144:ef7eb2e8f9f7 19 (+) Enable the RTC domain access (see description in the section above).
<> 144:ef7eb2e8f9f7 20 (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour
<> 144:ef7eb2e8f9f7 21 format using the HAL_RTC_Init() function.

<> 144:ef7eb2e8f9f7 23 *** Time and Date configuration ***
<> 144:ef7eb2e8f9f7 24 ===================================
<> 144:ef7eb2e8f9f7 25 [..]
<> 144:ef7eb2e8f9f7 26 (+) To configure the RTC Calendar (Time and Date) use the HAL_RTC_SetTime()
<> 144:ef7eb2e8f9f7 27 and HAL_RTC_SetDate() functions.
<> 144:ef7eb2e8f9f7 28 (+) To read the RTC Calendar, use the HAL_RTC_GetTime() and HAL_RTC_GetDate() functions.
<> 144:ef7eb2e8f9f7 29
<> 144:ef7eb2e8f9f7 30 *** Alarm configuration ***
<> 144:ef7eb2e8f9f7 31 ===========================
<> 144:ef7eb2e8f9f7 32 [..]
<> 144:ef7eb2e8f9f7 33 (+) To configure the RTC Alarm use the HAL_RTC_SetAlarm() function.
<> 144:ef7eb2e8f9f7 34 You can also configure the RTC Alarm with interrupt mode using the
<> 144:ef7eb2e8f9f7 35 HAL_RTC_SetAlarm_IT() function.
<> 144:ef7eb2e8f9f7 36 (+) To read the RTC Alarm, use the HAL_RTC_GetAlarm() function.
<> 144:ef7eb2e8f9f7 37
<> 144:ef7eb2e8f9f7 38 ##### RTC and low power modes #####
<> 144:ef7eb2e8f9f7 39 ===================================================================
<> 144:ef7eb2e8f9f7 40 [..] The MCU can be woken up from a low power mode by an RTC alternate
<> 144:ef7eb2e8f9f7 41 function.
<> 144:ef7eb2e8f9f7 42 [..] The RTC alternate functions are the RTC alarm (Alarm A),
<> 144:ef7eb2e8f9f7 43 RTC wake-up, RTC tamper event detection and RTC time stamp event detection.
<> 144:ef7eb2e8f9f7 44 These RTC alternate functions can wake up the system from the Stop and
<> 144:ef7eb2e8f9f7 45 Standby low power modes.
<> 144:ef7eb2e8f9f7 46 [..] The system can also wake up from low power modes without depending
<> 144:ef7eb2e8f9f7 47 on an external interrupt (Auto-wake-up mode), by using the RTC alarm
<> 144:ef7eb2e8f9f7 48 or the RTC wake-up events.
<> 144:ef7eb2e8f9f7 49 [..] The RTC provides a programmable time base for waking up from the
<> 144:ef7eb2e8f9f7 50 Stop or Standby mode at regular intervals.
<> 144:ef7eb2e8f9f7 51 Wake-up from STOP and STANDBY modes is possible only when the RTC clock source
<> 144:ef7eb2e8f9f7 52 is LSE or LSI.

<> 144:ef7eb2e8f9f7 117 [..] This section provides functions allowing to initialize and configure the
<> 144:ef7eb2e8f9f7 118 RTC Prescaler (Synchronous and Asynchronous), RTC Hour format, disable
<> 144:ef7eb2e8f9f7 119 RTC registers Write protection, enter and exit the RTC initialization mode,
<> 144:ef7eb2e8f9f7 120 RTC registers synchronization check and reference clock detection enable.
<> 144:ef7eb2e8f9f7 121 (#) The RTC Prescaler is programmed to generate the RTC 1Hz time base.
<> 144:ef7eb2e8f9f7 122 It is split into 2 programmable prescalers to minimize power consumption.
<> 144:ef7eb2e8f9f7 123 (++) A 7-bit asynchronous prescaler and a 15-bit synchronous prescaler.
<> 144:ef7eb2e8f9f7 124 (++) When both prescalers are used, it is recommended to configure the
<> 144:ef7eb2e8f9f7 125 asynchronous prescaler to a high value to minimize power consumption.
<> 144:ef7eb2e8f9f7 126 (#) All RTC registers are Write protected. Writing to the RTC registers
<> 144:ef7eb2e8f9f7 127 is enabled by writing a key into the Write Protection register, RTC_WPR.
<> 144:ef7eb2e8f9f7 128 (#) To configure the RTC Calendar, user application should enter
<> 144:ef7eb2e8f9f7 129 initialization mode. In this mode, the calendar counter is stopped
<> 144:ef7eb2e8f9f7 130 and its value can be updated. When the initialization sequence is
<> 144:ef7eb2e8f9f7 131 complete, the calendar restarts counting after 4 RTCCLK cycles.
<> 144:ef7eb2e8f9f7 132 (#) To read the calendar through the shadow registers after Calendar
<> 144:ef7eb2e8f9f7 133 initialization, calendar update or after wake-up from low power modes
<> 144:ef7eb2e8f9f7 134 the software must first clear the RSF flag. The software must then
<> 144:ef7eb2e8f9f7 135 wait until it is set again before reading the calendar, which means
<> 144:ef7eb2e8f9f7 136 that the calendar registers have been correctly copied into the
<> 144:ef7eb2e8f9f7 137 RTC_TR and RTC_DR shadow registers.The HAL_RTC_WaitForSynchro() function
