RTCOR is an 8-bit readable/writable register that sets the RTCNT compare-match interval.
RTCOR and RTCNT are constantly compared. When their values match, the CMF flag is set to 1
in RTMCSR, and RTCNT is simultaneously cleared to H'00.
RTCOR is initialized to H'FF by a reset and in hardware standby mode. It is not initialized in
software standby mode.
Note: Only byte access should be used with this register.
