phungductung 0:8ede47d38d10 17 ==============================================================================
phungductung 0:8ede47d38d10 18 ##### Backup Domain Operating Condition #####
phungductung 0:8ede47d38d10 19 ==============================================================================
phungductung 0:8ede47d38d10 20 [..] The real-time clock (RTC), the RTC backup registers, and the backup
phungductung 0:8ede47d38d10 21 SRAM (BKP SRAM) can be powered from the VBAT voltage when the main
phungductung 0:8ede47d38d10 22 VDD supply is powered off.
phungductung 0:8ede47d38d10 23 To retain the content of the RTC backup registers, backup SRAM, and supply
phungductung 0:8ede47d38d10 24 the RTC when VDD is turned off, VBAT pin can be connected to an optional
phungductung 0:8ede47d38d10 25 standby voltage supplied by a battery or by another source.
phungductung 0:8ede47d38d10 26
phungductung 0:8ede47d38d10 27 [..] To allow the RTC operating even when the main digital supply (VDD) is turned
phungductung 0:8ede47d38d10 28 off, the VBAT pin powers the following blocks:
phungductung 0:8ede47d38d10 29 (#) The RTC
phungductung 0:8ede47d38d10 30 (#) The LSE oscillator
phungductung 0:8ede47d38d10 31 (#) The backup SRAM when the low power backup regulator is enabled
phungductung 0:8ede47d38d10 32 (#) PC13 to PC15 I/Os, plus PI8 I/O (when available)
phungductung 0:8ede47d38d10 33
phungductung 0:8ede47d38d10 34 [..] When the backup domain is supplied by VDD (analog switch connected to VDD),
phungductung 0:8ede47d38d10 35 the following pins are available:
phungductung 0:8ede47d38d10 36 (#) PC14 and PC15 can be used as either GPIO or LSE pins
phungductung 0:8ede47d38d10 37 (#) PC13 can be used as a GPIO or as the RTC_AF1 pin
phungductung 0:8ede47d38d10 38 (#) PI8 can be used as a GPIO or as the RTC_AF2 pin
phungductung 0:8ede47d38d10 39
phungductung 0:8ede47d38d10 40 [..] When the backup domain is supplied by VBAT (analog switch connected to VBAT
phungductung 0:8ede47d38d10 41 because VDD is not present), the following pins are available:
phungductung 0:8ede47d38d10 42 (#) PC14 and PC15 can be used as LSE pins only
phungductung 0:8ede47d38d10 43 (#) PC13 can be used as the RTC_AF1 pin
phungductung 0:8ede47d38d10 44 (#) PI8 can be used as the RTC_AF2 pin
phungductung 0:8ede47d38d10 45 (#) PC1 can be used as the RTC_AF3 pin
phungductung 0:8ede47d38d10 46
phungductung 0:8ede47d38d10 47 ##### Backup Domain Reset #####
phungductung 0:8ede47d38d10 48 ==================================================================
phungductung 0:8ede47d38d10 49 [..] The backup domain reset sets all RTC registers and the RCC_BDCR register
phungductung 0:8ede47d38d10 50 to their reset values. The BKPSRAM is not affected by this reset. The only
phungductung 0:8ede47d38d10 51 way to reset the BKPSRAM is through the Flash interface by requesting
phungductung 0:8ede47d38d10 52 a protection level change from 1 to 0.
phungductung 0:8ede47d38d10 53 [..] A backup domain reset is generated when one of the following events occurs:
phungductung 0:8ede47d38d10 54 (#) Software reset, triggered by setting the BDRST bit in the
phungductung 0:8ede47d38d10 55 RCC Backup domain control register (RCC_BDCR).
phungductung 0:8ede47d38d10 56 (#) VDD or VBAT power on, if both supplies have previously been powered off.
phungductung 0:8ede47d38d10 57
phungductung 0:8ede47d38d10 58 ##### Backup Domain Access #####
phungductung 0:8ede47d38d10 59 ==================================================================
phungductung 0:8ede47d38d10 60 [..] After reset, the backup domain (RTC registers, RTC backup data
phungductung 0:8ede47d38d10 61 registers and backup SRAM) is protected against possible unwanted write
phungductung 0:8ede47d38d10 62 accesses.
phungductung 0:8ede47d38d10 63 [..] To enable access to the RTC Domain and RTC registers, proceed as follows:
phungductung 0:8ede47d38d10 64 (+) Enable the Power Controller (PWR) APB1 interface clock using the
phungductung 0:8ede47d38d10 65 __HAL_RCC_PWR_CLK_ENABLE() function.
phungductung 0:8ede47d38d10 66 (+) Enable access to RTC domain using the HAL_PWR_EnableBkUpAccess() function.
phungductung 0:8ede47d38d10 67 (+) Select the RTC clock source using the __HAL_RCC_RTC_CONFIG() function.
phungductung 0:8ede47d38d10 68 (+) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() function.
phungductung 0:8ede47d38d10 69
phungductung 0:8ede47d38d10 70
phungductung 0:8ede47d38d10 71 ##### How to use this driver #####
phungductung 0:8ede47d38d10 72 ==================================================================
phungductung 0:8ede47d38d10 73 [..]
phungductung 0:8ede47d38d10 74 (+) Enable the RTC domain access (see description in the section above).
phungductung 0:8ede47d38d10 75 (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour
phungductung 0:8ede47d38d10 76 format using the HAL_RTC_Init() function.
phungductung 0:8ede47d38d10 77
phungductung 0:8ede47d38d10 78 *** Time and Date configuration ***
phungductung 0:8ede47d38d10 79 ===================================
phungductung 0:8ede47d38d10 80 [..]
phungductung 0:8ede47d38d10 81 (+) To configure the RTC Calendar (Time and Date) use the HAL_RTC_SetTime()
phungductung 0:8ede47d38d10 82 and HAL_RTC_SetDate() functions.
phungductung 0:8ede47d38d10 83 (+) To read the RTC Calendar, use the HAL_RTC_GetTime() and HAL_RTC_GetDate() functions.
phungductung 0:8ede47d38d10 84
phungductung 0:8ede47d38d10 85 *** Alarm configuration ***
phungductung 0:8ede47d38d10 86 ===========================
phungductung 0:8ede47d38d10 87 [..]
phungductung 0:8ede47d38d10 88 (+) To configure the RTC Alarm use the HAL_RTC_SetAlarm() function.
phungductung 0:8ede47d38d10 89 You can also configure the RTC Alarm with interrupt mode using the HAL_RTC_SetAlarm_IT() function.
phungductung 0:8ede47d38d10 90 (+) To read the RTC Alarm, use the HAL_RTC_GetAlarm() function.
phungductung 0:8ede47d38d10 91
phungductung 0:8ede47d38d10 92 ##### RTC and low power modes #####
phungductung 0:8ede47d38d10 93 ==================================================================
phungductung 0:8ede47d38d10 94 [..] The MCU can be woken up from a low power mode by an RTC alternate
phungductung 0:8ede47d38d10 95 function.
phungductung 0:8ede47d38d10 96 [..] The RTC alternate functions are the RTC alarms (Alarm A and Alarm B),
phungductung 0:8ede47d38d10 97 RTC wakeup, RTC tamper event detection and RTC time stamp event detection.
phungductung 0:8ede47d38d10 98 These RTC alternate functions can wake up the system from the Stop and
phungductung 0:8ede47d38d10 99 Standby low power modes.
phungductung 0:8ede47d38d10 100 [..] The system can also wake up from low power modes without depending
phungductung 0:8ede47d38d10 101 on an external interrupt (Auto-wakeup mode), by using the RTC alarm
phungductung 0:8ede47d38d10 102 or the RTC wakeup events.
phungductung 0:8ede47d38d10 103 [..] The RTC provides a programmable time base for waking up from the
phungductung 0:8ede47d38d10 104 Stop or Standby mode at regular intervals.
phungductung 0:8ede47d38d10 105 Wakeup from STOP and STANDBY modes is possible only when the RTC clock source
phungductung 0:8ede47d38d10 106 is LSE or LSI.

phungductung 0:8ede47d38d10 170 ===============================================================================
phungductung 0:8ede47d38d10 171 [..] This section provides functions allowing to initialize and configure the
phungductung 0:8ede47d38d10 172 RTC Prescaler (Synchronous and Asynchronous), RTC Hour format, disable
phungductung 0:8ede47d38d10 173 RTC registers Write protection, enter and exit the RTC initialization mode,
phungductung 0:8ede47d38d10 174 RTC registers synchronization check and reference clock detection enable.
phungductung 0:8ede47d38d10 175 (#) The RTC Prescaler is programmed to generate the RTC 1Hz time base.
phungductung 0:8ede47d38d10 176 It is split into 2 programmable prescalers to minimize power consumption.
phungductung 0:8ede47d38d10 177 (++) A 7-bit asynchronous prescaler and a 13-bit synchronous prescaler.
phungductung 0:8ede47d38d10 178 (++) When both prescalers are used, it is recommended to configure the
phungductung 0:8ede47d38d10 179 asynchronous prescaler to a high value to minimize power consumption.
phungductung 0:8ede47d38d10 180 (#) All RTC registers are Write protected. Writing to the RTC registers
phungductung 0:8ede47d38d10 181 is enabled by writing a key into the Write Protection register, RTC_WPR.
phungductung 0:8ede47d38d10 182 (#) To configure the RTC Calendar, user application should enter
phungductung 0:8ede47d38d10 183 initialization mode. In this mode, the calendar counter is stopped
phungductung 0:8ede47d38d10 184 and its value can be updated. When the initialization sequence is
phungductung 0:8ede47d38d10 185 complete, the calendar restarts counting after 4 RTCCLK cycles.
phungductung 0:8ede47d38d10 186 (#) To read the calendar through the shadow registers after Calendar
phungductung 0:8ede47d38d10 187 initialization, calendar update or after wakeup from low power modes
phungductung 0:8ede47d38d10 188 the software must first clear the RSF flag. The software must then
phungductung 0:8ede47d38d10 189 wait until it is set again before reading the calendar, which means
phungductung 0:8ede47d38d10 190 that the calendar registers have been correctly copied into the
phungductung 0:8ede47d38d10 191 RTC_TR and RTC_DR shadow registers.The HAL_RTC_WaitForSynchro() function
phungductung 0:8ede47d38d10 192 implements the above software sequence (RSF clear and RSF check).
