RTC Control Register
Name:
Access Type:
• UPDTIM: Update Request Time Register
0 = No effect.
1 = Stops the RTC time counting.
Time counting consists of second, minute and hour counters. Time counters can be programmed once this bit is set and
acknowledged by the bit ACKUPD of the Status Register.
• UPDCAL: Update Request Calendar Register
0 = No effect.
1 = Stops the RTC calendar counting.
Calendar counting consists of day, date, month, year and century counters. Calendar counters can be programmed once
this bit is set.
• TIMEVSEL: Time Event Selection
The event that generates the flag TIMEV in RTC_SR (Status Register) depends on the value of TIMEVSEL.
0 = Minute change.
1 = Hour change.
2 = Every day at midnight.
3 = Every day at noon.
• CALEVSEL: Calendar Event Selection
The event that generates the flag CALEV in RTC_SR depends on the value of CALEVSEL.
0 = Week change (every Monday at time 00:00:00).
1 = Month change (every 01 of each month at time 00:00:00).
2, 3 = Year change (every January 1 at time 00:00:00).
