Function Descriptions
Table 158. MCC_RTC_Timer
Notes:
– The MCC/ RTC interrupt wakes up the MCU from ACTIVE-HALT mode, not from HALT
– A modification of time base is taken into account at the end of the current period (previously

MCC_RTC_Timer
Void MCC_RTC_Timer (MCC_RTC_Param Timer_Value)
Selects the programmable divider time base. Oscillator in-
terrupts are generated, as per the timebase selection. You
have to select the input values from the table shown be-
