<> 144:ef7eb2e8f9f7 17 ==============================================================================
<> 144:ef7eb2e8f9f7 18 ##### Backup Domain Operating Condition #####
<> 144:ef7eb2e8f9f7 19 ==============================================================================
<> 144:ef7eb2e8f9f7 20 [..] The real-time clock (RTC), the RTC backup registers, and the backup
<> 144:ef7eb2e8f9f7 21 SRAM (BKP SRAM) can be powered from the VBAT voltage when the main
<> 144:ef7eb2e8f9f7 22 VDD supply is powered off.
<> 144:ef7eb2e8f9f7 23 To retain the content of the RTC backup registers, backup SRAM, and supply
<> 144:ef7eb2e8f9f7 24 the RTC when VDD is turned off, VBAT pin can be connected to an optional
<> 144:ef7eb2e8f9f7 25 standby voltage supplied by a battery or by another source.
<> 144:ef7eb2e8f9f7 26
<> 144:ef7eb2e8f9f7 27 [..] To allow the RTC operating even when the main digital supply (VDD) is turned
<> 144:ef7eb2e8f9f7 28 off, the VBAT pin powers the following blocks:
<> 144:ef7eb2e8f9f7 29 (#) The RTC
<> 144:ef7eb2e8f9f7 30 (#) The LSE oscillator
<> 144:ef7eb2e8f9f7 31 (#) The backup SRAM when the low power backup regulator is enabled
<> 144:ef7eb2e8f9f7 32 (#) PC13 to PC15 I/Os, plus PI8 I/O (when available)
<> 144:ef7eb2e8f9f7 33
<> 144:ef7eb2e8f9f7 34 [..] When the backup domain is supplied by VDD (analog switch connected to VDD),
<> 144:ef7eb2e8f9f7 35 the following pins are available:
<> 144:ef7eb2e8f9f7 36 (#) PC14 and PC15 can be used as either GPIO or LSE pins
<> 144:ef7eb2e8f9f7 37 (#) PC13 can be used as a GPIO or as the RTC_AF1 pin
<> 144:ef7eb2e8f9f7 38 (#) PI8 can be used as a GPIO or as the RTC_AF2 pin
<> 144:ef7eb2e8f9f7 39
<> 144:ef7eb2e8f9f7 40 [..] When the backup domain is supplied by VBAT (analog switch connected to VBAT
<> 144:ef7eb2e8f9f7 41 because VDD is not present), the following pins are available:
<> 144:ef7eb2e8f9f7 42 (#) PC14 and PC15 can be used as LSE pins only
<> 144:ef7eb2e8f9f7 43 (#) PC13 can be used as the RTC_AF1 pin
<> 144:ef7eb2e8f9f7 44 (#) PI8 can be used as the RTC_AF2 pin
<> 144:ef7eb2e8f9f7 45
<> 144:ef7eb2e8f9f7 46 ##### Backup Domain Reset #####
<> 144:ef7eb2e8f9f7 47 ==================================================================
<> 144:ef7eb2e8f9f7 48 [..] The backup domain reset sets all RTC registers and the RCC_BDCR register
<> 144:ef7eb2e8f9f7 49 to their reset values. The BKPSRAM is not affected by this reset. The only
<> 144:ef7eb2e8f9f7 50 way to reset the BKPSRAM is through the Flash interface by requesting
<> 144:ef7eb2e8f9f7 51 a protection level change from 1 to 0.
<> 144:ef7eb2e8f9f7 52 [..] A backup domain reset is generated when one of the following events occurs:
<> 144:ef7eb2e8f9f7 53 (#) Software reset, triggered by setting the BDRST bit in the
<> 144:ef7eb2e8f9f7 54 RCC Backup domain control register (RCC_BDCR).
<> 144:ef7eb2e8f9f7 55 (#) VDD or VBAT power on, if both supplies have previously been powered off.
<> 144:ef7eb2e8f9f7 56
<> 144:ef7eb2e8f9f7 57 ##### Backup Domain Access #####
<> 144:ef7eb2e8f9f7 58 ==================================================================
<> 144:ef7eb2e8f9f7 59 [..] After reset, the backup domain (RTC registers, RTC backup data
<> 144:ef7eb2e8f9f7 60 registers and backup SRAM) is protected against possible unwanted write
<> 144:ef7eb2e8f9f7 61 accesses.
<> 144:ef7eb2e8f9f7 62 [..] To enable access to the RTC Domain and RTC registers, proceed as follows:
<> 144:ef7eb2e8f9f7 63 (+) Enable the Power Controller (PWR) APB1 interface clock using the
<> 144:ef7eb2e8f9f7 64 __HAL_RCC_PWR_CLK_ENABLE() function.
<> 144:ef7eb2e8f9f7 65 (+) Enable access to RTC domain using the HAL_PWR_EnableBkUpAccess() function.
<> 144:ef7eb2e8f9f7 66 (+) Select the RTC clock source using the __HAL_RCC_RTC_CONFIG() function.
<> 144:ef7eb2e8f9f7 67 (+) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() function.
<> 144:ef7eb2e8f9f7 68
<> 144:ef7eb2e8f9f7 69
<> 144:ef7eb2e8f9f7 70 ##### How to use this driver #####
<> 144:ef7eb2e8f9f7 71 ==================================================================
<> 144:ef7eb2e8f9f7 72 [..]
<> 144:ef7eb2e8f9f7 73 (+) Enable the RTC domain access (see description in the section above).
<> 144:ef7eb2e8f9f7 74 (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour
<> 144:ef7eb2e8f9f7 75 format using the HAL_RTC_Init() function.
<> 144:ef7eb2e8f9f7 76
<> 144:ef7eb2e8f9f7 77 *** Time and Date configuration ***
<> 144:ef7eb2e8f9f7 78 ===================================
<> 144:ef7eb2e8f9f7 79 [..]
<> 144:ef7eb2e8f9f7 80 (+) To configure the RTC Calendar (Time and Date) use the HAL_RTC_SetTime()
<> 144:ef7eb2e8f9f7 81 and HAL_RTC_SetDate() functions.
<> 144:ef7eb2e8f9f7 82 (+) To read the RTC Calendar, use the HAL_RTC_GetTime() and HAL_RTC_GetDate() functions.
<> 144:ef7eb2e8f9f7 83
<> 144:ef7eb2e8f9f7 84 *** Alarm configuration ***
<> 144:ef7eb2e8f9f7 85 ===========================
<> 144:ef7eb2e8f9f7 86 [..]
<> 144:ef7eb2e8f9f7 87 (+) To configure the RTC Alarm use the HAL_RTC_SetAlarm() function.
<> 144:ef7eb2e8f9f7 88 You can also configure the RTC Alarm with interrupt mode using the HAL_RTC_SetAlarm_IT() function.
<> 144:ef7eb2e8f9f7 89 (+) To read the RTC Alarm, use the HAL_RTC_GetAlarm() function.
<> 144:ef7eb2e8f9f7 90
<> 144:ef7eb2e8f9f7 91 ##### RTC and low power modes #####
<> 144:ef7eb2e8f9f7 92 ==================================================================
<> 144:ef7eb2e8f9f7 93 [..] The MCU can be woken up from a low power mode by an RTC alternate
<> 144:ef7eb2e8f9f7 94 function.
<> 144:ef7eb2e8f9f7 95 [..] The RTC alternate functions are the RTC alarms (Alarm A and Alarm B),
<> 144:ef7eb2e8f9f7 96 RTC wake-up, RTC tamper event detection and RTC time stamp event detection.
<> 144:ef7eb2e8f9f7 97 These RTC alternate functions can wake up the system from the Stop and
<> 144:ef7eb2e8f9f7 98 Standby low power modes.
<> 144:ef7eb2e8f9f7 99 [..] The system can also wake up from low power modes without depending
<> 144:ef7eb2e8f9f7 100 on an external interrupt (Auto-wake-up mode), by using the RTC alarm
<> 144:ef7eb2e8f9f7 101 or the RTC wake-up events.
<> 144:ef7eb2e8f9f7 102 [..] The RTC provides a programmable time base for waking up from the
<> 144:ef7eb2e8f9f7 103 Stop or Standby mode at regular intervals.
<> 144:ef7eb2e8f9f7 104 Wake-up from STOP and STANDBY modes is possible only when the RTC clock source
<> 144:ef7eb2e8f9f7 105 is LSE or LSI.

<> 144:ef7eb2e8f9f7 174 (#) The RTC Prescaler is programmed to generate the RTC 1Hz time base.

<> 144:ef7eb2e8f9f7 176 (++) A 7-bit asynchronous prescaler and a 13-bit synchronous prescaler.
<> 144:ef7eb2e8f9f7 177 (++) When both prescalers are used, it is recommended to configure the
<> 144:ef7eb2e8f9f7 178 asynchronous prescaler to a high value to minimize power consumption.
<> 144:ef7eb2e8f9f7 179 (#) All RTC registers are Write protected. Writing to the RTC registers
<> 144:ef7eb2e8f9f7 180 is enabled by writing a key into the Write Protection register, RTC_WPR.
<> 144:ef7eb2e8f9f7 181 (#) To configure the RTC Calendar, user application should enter
<> 144:ef7eb2e8f9f7 182 initialization mode. In this mode, the calendar counter is stopped
