Description
Compare Match Interrupt Enable
Enables or disables CMF interrupt requests when the
CMF bit in RTCSR is set to 1.
0: Disables CMF interrupt requests.
1: Enables CMF interrupt requests.
Clock Select
Select the clock input to count-up the refresh timer
counter (RTCNT).
000: Stop the counting-up

111: Bφ/4096
Refresh Count
Specify the number of continuous refresh cycles, when
the refresh request occurs after the coincidence of the
values of the refresh timer counter (RTCNT) and the
refresh time constant register (RTCOR). These bits can
make the period of occurrence of refresh long.
