RTCNT is write-disabled when the PSRAME bit or DRAME bit is set to 1. RTCNT is initialized
to H'00 by a reset and in standby mode.
7.2.4
RTCOR is an 8-bit readable/writable register that determines the interval at which RTCNT is
compare matched.
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 write-disabled when the PSRAME bit or DRAME bit is set to 1. RTCOR is initialized
to H'FF by a reset and in hardware standby mode. In software standby mode it retains its previous
value.
