Bits 5 to 3—Refresh Counter Clock Select (CKS2 to CKS0): These bits select the clock to be
input to RTCNT from among 7 clocks obtained by dividing the system clock ( ). When the input
clock is selected with bits CKS2 to CKS0, RTCNT begins counting up.

Bits 2 to 0—Reserved: These bits cannot be modified and are always read as 1.
6.2.10
RTCNT is an 8-bit readable/writable up-counter.
RTCNT is incremented by an internal clock selected by bits CKS2 to CKS0 in RTMCSR. When
RTCNT matches RTCOR (compare match), the CMF flag in RTMCSR is set to 1 and RTCNT is
cleared to H'00. If the RCYCE bit in DRCRB is set to 1 at this time, a refresh cycle is started.
Also, if the CMIE bit in RTMCSR is set to 1, a compare match interrupt (CMI) is generated.
RTCNT is initialized to H'00 by a reset and in standby mode.
