<> 144:ef7eb2e8f9f7 20 [..]
<> 144:ef7eb2e8f9f7 21 (+) Enable the RTC domain access.
<> 144:ef7eb2e8f9f7 22 (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour
<> 144:ef7eb2e8f9f7 23 format using the HAL_RTC_Init() function.

<> 144:ef7eb2e8f9f7 27 [..]
<> 144:ef7eb2e8f9f7 28 (+) To configure the RTC Wake-up Clock source and Counter use the HAL_RTC_SetWakeUpTimer()
<> 144:ef7eb2e8f9f7 29 function. You can also configure the RTC Wake-up timer in interrupt mode
<> 144:ef7eb2e8f9f7 30 using the HAL_RTC_SetWakeUpTimer_IT() function.

<> 144:ef7eb2e8f9f7 41 function.
<> 144:ef7eb2e8f9f7 42 (+) The TIMESTAMP alternate function can be mapped either to RTC_AF1 (PC13)

<> 144:ef7eb2e8f9f7 54 mode using HAL_RTC_SetTamper_IT() function.
<> 144:ef7eb2e8f9f7 55 (+) The TAMPER1 alternate function can be mapped either to RTC_AF1 (PC13)
<> 144:ef7eb2e8f9f7 56 or RTC_AF2 (PI8 or PA0 only for STM32F446xx devices) depending on the value of TAMP1INSEL bit in
<> 144:ef7eb2e8f9f7 57 RTC_TAFCR register. The corresponding pin is also selected by HAL_RTC_SetTamper()
