9.2.17
RTCNT counts up on the internal clock selected by bits RTCK2 to RTCK0 in REFCR.
When the RTCNT value matches the RTCOR value (compare match), the CMF flag in REFCR is
set to 1 and RTCNT is initialized to H'00. At this time, when the RFSHE bit in REFCR is set to 1,
a refresh cycle is generated. When the RFSHE bit is cleared to 0 and the CMIE bit in REFCR is
set to 1, a compare match interrupt (CMI) is generated.
9.2.18
RTCOR specifies intervals at which a compare match for RTCOR and RTCNT is generated.
The RTCOR value is always compared with the RTCNT value. When they match, the CMF flag
in REFCR is set to 1 and RTCNT is initialized to H'00.
