6.2.9
RTCOR is an 8-bit readable/writable register that sets the period for compare match operations with RTCNT.
The values of RTCOR and RTCNT are constantly compared, and if they match, the CMF flag in DRAMCR is set to 1 and
RTCNT is cleared to H'00.
RTCOR is initialized to H'FF by a power-on reset and in hardware standby mode. It is not initialized by a manual reset* or
in software standby mode.
Note: * Manual reset is only supported in the H8S/2357 ZTAT.
