Rtc Timestamp And Tamper Functions; Rtc Wake-Up Functions; Extension Peripheral Control Functions - ST STM32F2 User Manual

HAL RTC Extension Driver
Tamper configuration
Enable the RTC Tamper and configure the trigger using the
HAL_RTCEx_SetTamper() function. You can configure RTC Tamper in interrupt mode
using HAL_RTCEx_SetTamper_IT() function.
The TAMPER1 alternate function can be mapped either to RTC_AF1 (PC13) or
RTC_AF2 (PI8) depending on the value of TAMP1INSEL bit in RTC_TAFCR register.
The corresponding pin is also selected by HAL_RTCEx_SetTamper() or
HAL_RTCEx_SetTamper_IT() function.
Backup Data Registers configuration
To write to the RTC Backup Data registers, use the HAL_RTCEx_BKUPWrite()
function.
To read the RTC Backup Data registers, use the HAL_RTCEx_BKUPRead() function.
