phungductung	0:e87aa4c49e95	17	==============================================================================
phungductung	0:e87aa4c49e95	18	##### Backup Domain Operating Condition #####
phungductung	0:e87aa4c49e95	19	==============================================================================
phungductung	0:e87aa4c49e95	20	[..] The real-time clock (RTC), the RTC backup registers, and the backup
phungductung	0:e87aa4c49e95	21	SRAM (BKP SRAM) can be powered from the VBAT voltage when the main
phungductung	0:e87aa4c49e95	22	VDD supply is powered off.
phungductung	0:e87aa4c49e95	23	To retain the content of the RTC backup registers, backup SRAM, and supply
phungductung	0:e87aa4c49e95	24	the RTC when VDD is turned off, VBAT pin can be connected to an optional
phungductung	0:e87aa4c49e95	25	standby voltage supplied by a battery or by another source.
phungductung	0:e87aa4c49e95	26
phungductung	0:e87aa4c49e95	27	[..] To allow the RTC operating even when the main digital supply (VDD) is turned
phungductung	0:e87aa4c49e95	28	off, the VBAT pin powers the following blocks:
phungductung	0:e87aa4c49e95	29	(#) The RTC
phungductung	0:e87aa4c49e95	30	(#) The LSE oscillator
phungductung	0:e87aa4c49e95	31	(#) The backup SRAM when the low power backup regulator is enabled
phungductung	0:e87aa4c49e95	32	(#) PC13 to PC15 I/Os, plus PI8 I/O (when available)
phungductung	0:e87aa4c49e95	33
phungductung	0:e87aa4c49e95	34	[..] When the backup domain is supplied by VDD (analog switch connected to VDD),
phungductung	0:e87aa4c49e95	35	the following pins are available:
phungductung	0:e87aa4c49e95	36	(#) PC14 and PC15 can be used as either GPIO or LSE pins
phungductung	0:e87aa4c49e95	37	(#) PC13 can be used as a GPIO or as the RTC_AF1 pin
phungductung	0:e87aa4c49e95	38	(#) PI8 can be used as a GPIO or as the RTC_AF2 pin
phungductung	0:e87aa4c49e95	39
phungductung	0:e87aa4c49e95	40	[..] When the backup domain is supplied by VBAT (analog switch connected to VBAT
phungductung	0:e87aa4c49e95	41	because VDD is not present), the following pins are available:
phungductung	0:e87aa4c49e95	42	(#) PC14 and PC15 can be used as LSE pins only
phungductung	0:e87aa4c49e95	43	(#) PC13 can be used as the RTC_AF1 pin
phungductung	0:e87aa4c49e95	44	(#) PI8 can be used as the RTC_AF2 pin
phungductung	0:e87aa4c49e95	45	(#) PC1 can be used as the RTC_AF3 pin
phungductung	0:e87aa4c49e95	46
phungductung	0:e87aa4c49e95	47	##### Backup Domain Reset #####
phungductung	0:e87aa4c49e95	48	==================================================================
phungductung	0:e87aa4c49e95	49	[..] The backup domain reset sets all RTC registers and the RCC_BDCR register
phungductung	0:e87aa4c49e95	50	to their reset values. The BKPSRAM is not affected by this reset. The only
phungductung	0:e87aa4c49e95	51	way to reset the BKPSRAM is through the Flash interface by requesting
phungductung	0:e87aa4c49e95	52	a protection level change from 1 to 0.
phungductung	0:e87aa4c49e95	53	[..] A backup domain reset is generated when one of the following events occurs:
phungductung	0:e87aa4c49e95	54	(#) Software reset, triggered by setting the BDRST bit in the
phungductung	0:e87aa4c49e95	55	RCC Backup domain control register (RCC_BDCR).
phungductung	0:e87aa4c49e95	56	(#) VDD or VBAT power on, if both supplies have previously been powered off.
phungductung	0:e87aa4c49e95	57
phungductung	0:e87aa4c49e95	58	##### Backup Domain Access #####
phungductung	0:e87aa4c49e95	59	==================================================================
phungductung	0:e87aa4c49e95	60	[..] After reset, the backup domain (RTC registers, RTC backup data
phungductung	0:e87aa4c49e95	61	registers and backup SRAM) is protected against possible unwanted write
phungductung	0:e87aa4c49e95	62	accesses.
phungductung	0:e87aa4c49e95	63	[..] To enable access to the RTC Domain and RTC registers, proceed as follows:
phungductung	0:e87aa4c49e95	64	(+) Enable the Power Controller (PWR) APB1 interface clock using the
phungductung	0:e87aa4c49e95	65	__HAL_RCC_PWR_CLK_ENABLE() function.
phungductung	0:e87aa4c49e95	66	(+) Enable access to RTC domain using the HAL_PWR_EnableBkUpAccess() function.
phungductung	0:e87aa4c49e95	67	(+) Select the RTC clock source using the __HAL_RCC_RTC_CONFIG() function.
phungductung	0:e87aa4c49e95	68	(+) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() function.
phungductung	0:e87aa4c49e95	69
phungductung	0:e87aa4c49e95	70
phungductung	0:e87aa4c49e95	71	##### How to use this driver #####
phungductung	0:e87aa4c49e95	72	==================================================================
phungductung	0:e87aa4c49e95	73	[..]
phungductung	0:e87aa4c49e95	74	(+) Enable the RTC domain access (see description in the section above).
phungductung	0:e87aa4c49e95	75	(+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour
phungductung	0:e87aa4c49e95	76	format using the HAL_RTC_Init() function.
phungductung	0:e87aa4c49e95	77
phungductung	0:e87aa4c49e95	78	* Time and Date configuration *
phungductung	0:e87aa4c49e95	79	===================================
phungductung	0:e87aa4c49e95	80	[..]
phungductung	0:e87aa4c49e95	81	(+) To configure the RTC Calendar (Time and Date) use the HAL_RTC_SetTime()
phungductung	0:e87aa4c49e95	82	and HAL_RTC_SetDate() functions.
phungductung	0:e87aa4c49e95	83	(+) To read the RTC Calendar, use the HAL_RTC_GetTime() and HAL_RTC_GetDate() functions.
phungductung	0:e87aa4c49e95	84
phungductung	0:e87aa4c49e95	85	* Alarm configuration *
phungductung	0:e87aa4c49e95	86	===========================
phungductung	0:e87aa4c49e95	87	[..]
phungductung	0:e87aa4c49e95	88	(+) To configure the RTC Alarm use the HAL_RTC_SetAlarm() function.
phungductung	0:e87aa4c49e95	89	You can also configure the RTC Alarm with interrupt mode using the HAL_RTC_SetAlarm_IT() function.
phungductung	0:e87aa4c49e95	90	(+) To read the RTC Alarm, use the HAL_RTC_GetAlarm() function.
phungductung	0:e87aa4c49e95	91
phungductung	0:e87aa4c49e95	92	##### RTC and low power modes #####
phungductung	0:e87aa4c49e95	93	==================================================================
phungductung	0:e87aa4c49e95	94	[..] The MCU can be woken up from a low power mode by an RTC alternate
phungductung	0:e87aa4c49e95	95	function.
phungductung	0:e87aa4c49e95	96	[..] The RTC alternate functions are the RTC alarms (Alarm A and Alarm B),
phungductung	0:e87aa4c49e95	97	RTC wakeup, RTC tamper event detection and RTC time stamp event detection.
phungductung	0:e87aa4c49e95	98	These RTC alternate functions can wake up the system from the Stop and
phungductung	0:e87aa4c49e95	99	Standby low power modes.
phungductung	0:e87aa4c49e95	100	[..] The system can also wake up from low power modes without depending
phungductung	0:e87aa4c49e95	101	on an external interrupt (Auto-wakeup mode), by using the RTC alarm
phungductung	0:e87aa4c49e95	102	or the RTC wakeup events.
phungductung	0:e87aa4c49e95	103	[..] The RTC provides a programmable time base for waking up from the
phungductung	0:e87aa4c49e95	104	Stop or Standby mode at regular intervals.
phungductung	0:e87aa4c49e95	105	Wakeup from STOP and STANDBY modes is possible only when the RTC clock source
phungductung	0:e87aa4c49e95	106	is LSE or LSI.

phungductung	0:e87aa4c49e95	170	===============================================================================
phungductung	0:e87aa4c49e95	171	[..] This section provides functions allowing to initialize and configure the
phungductung	0:e87aa4c49e95	172	RTC Prescaler (Synchronous and Asynchronous), RTC Hour format, disable
phungductung	0:e87aa4c49e95	173	RTC registers Write protection, enter and exit the RTC initialization mode,
phungductung	0:e87aa4c49e95	174	RTC registers synchronization check and reference clock detection enable.
phungductung	0:e87aa4c49e95	175	(#) The RTC Prescaler is programmed to generate the RTC 1Hz time base.
phungductung	0:e87aa4c49e95	176	It is split into 2 programmable prescalers to minimize power consumption.
phungductung	0:e87aa4c49e95	177	(++) A 7-bit asynchronous prescaler and a 13-bit synchronous prescaler.
phungductung	0:e87aa4c49e95	178	(++) When both prescalers are used, it is recommended to configure the
phungductung	0:e87aa4c49e95	179	asynchronous prescaler to a high value to minimize power consumption.
phungductung	0:e87aa4c49e95	180	(#) All RTC registers are Write protected. Writing to the RTC registers
phungductung	0:e87aa4c49e95	181	is enabled by writing a key into the Write Protection register, RTC_WPR.
phungductung	0:e87aa4c49e95	182	(#) To configure the RTC Calendar, user application should enter
phungductung	0:e87aa4c49e95	183	initialization mode. In this mode, the calendar counter is stopped
phungductung	0:e87aa4c49e95	184	and its value can be updated. When the initialization sequence is
phungductung	0:e87aa4c49e95	185	complete, the calendar restarts counting after 4 RTCCLK cycles.
phungductung	0:e87aa4c49e95	186	(#) To read the calendar through the shadow registers after Calendar
phungductung	0:e87aa4c49e95	187	initialization, calendar update or after wakeup from low power modes
phungductung	0:e87aa4c49e95	188	the software must first clear the RSF flag. The software must then
phungductung	0:e87aa4c49e95	189	wait until it is set again before reading the calendar, which means
