13.2.12 Refresh Count Register (RFCR)
The refresh count register (RFCR) is a 10-bit readable/writable counter that counts the number of
refreshes by being incremented each time the RTCOR register and RTCNT counter values match.
If the RFCR register value exceeds the count limit specified by the LMTS bit in the RTCSR
register, the OVF flag is set in the RTCSR register and the RFCR register is cleared.
RFCR is initialized to H'0000 by a power-on reset, but is not initialized, and retains its contents, in
a manual reset and in standby mode.
