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

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