Description
Reserved
These bits are always read as 0.
Compare-Match Flag
Status flag that indicates a match between RTCNT and
RTCOR values.
0: RTCNT and RTCOR values do not match
[Clearing condition]
When 0 is written to CMF
1: RTCNT and RTCOR values match
[Setting condition]
When RTCNT = RTCOR*
Compare-Match Interrupt Enable
Controls whether or not an interrupt request is enabled
when the CMF bit is set to 1 in RTCSR. Do not set this
bit to 1 when auto-refreshing is used.
0: Interrupt request by CMF disabled
1: Interrupt request by CMF enabled
