 ===============================================================================  

    [..] This section provide functions allowing to program and read the RTC WakeUp.

Function Documentation

uint32_t RTC_GetWakeUpCounter ( void  )

Returns the RTC WakeUp timer counter value.

Parameters
None
Return values
TheRTC WakeUp Counter value.
void RTC_SetWakeUpCounter ( uint32_t  RTC_WakeUpCounter)

Configures the RTC Wakeup counter.

Note
The RTC WakeUp counter can only be written when the RTC WakeUp is disabled (Use the RTC_WakeUpCmd(DISABLE)).
Parameters
RTC_WakeUpCounter,:specifies the WakeUp counter. This parameter can be a value from 0x0000 to 0xFFFF.
Return values
None
void RTC_WakeUpClockConfig ( uint32_t  RTC_WakeUpClock)

Configures the RTC Wakeup clock source.

Note
The WakeUp Clock source can only be changed when the RTC WakeUp is disabled (Use the RTC_WakeUpCmd(DISABLE)).
Parameters
RTC_WakeUpClock,:Wakeup Clock source. This parameter can be one of the following values:
  • RTC_WakeUpClock_RTCCLK_Div16
  • RTC_WakeUpClock_RTCCLK_Div8
  • RTC_WakeUpClock_RTCCLK_Div4
  • RTC_WakeUpClock_RTCCLK_Div2
  • RTC_WakeUpClock_CK_SPRE_16bits
  • RTC_WakeUpClock_CK_SPRE_17bits
Return values
None
ErrorStatus RTC_WakeUpCmd ( FunctionalState  NewState)

Enables or Disables the RTC WakeUp timer.

Parameters
NewState,:new state of the WakeUp timer. This parameter can be: ENABLE or DISABLE.
Return values
None
