Detailed Description

Function Documentation

void RTC_ClearFlag ( uint16_t  RTC_FLAG)

Clears the RTC's pending flags.

Parameters
RTC_FLAG,:specifies the flag to clear. This parameter can be any combination of the following values:
  • RTC_FLAG_RSF: Registers Synchronized flag. This flag is cleared only after an APB reset or an APB Clock stop.
  • RTC_FLAG_OW: Overflow flag
  • RTC_FLAG_ALR: Alarm flag
  • RTC_FLAG_SEC: Second flag
Return values
None
