? UPDTIM:
Writing 1 requests the RTC to stop the time counter so that it can be safely updated. The time counter is actually stopped
only when ACKUPD is set in RTC_SR.
Writing 0 restarts the time counter.
? UPDCAL:
Writing 1 requests the RTC to stop the calendar counter so that it can be safely updated. The calendar counter is actually
stopped only when ACKUPD is set in RTC_SR.
Writing 0 restarts the calendar counter.
? TIMEVSEL:
Selects the type of event to cause TIMEV to change in RTC_SR.
