13.2.3
The minute counter (RMINCNT) is an 8-bit readable/writable register used for setting/counting in
the BCD-coded minute section of the RTC. The count operation is performed by a carry for each
minute of the second counter.
The range that can be set is 00–59 (decimal). Errant operation will result if any other value is set.
Carry out write processing after halting the count operation with the START bit in RCR2.
RMINCNT is not initialized by a power-on reset or manual reset, or in standby mode.
13.2.4
The hour counter (RHRCNT) is an 8-bit readable/writable register used for setting/counting in the
BCD-coded hour section of the RTC. The count operation is performed by a carry for each 1 hour
of the minute counter.
The range that can be set is 00–23 (decimal). Errant operation will result if any other value is set.
Carry out write processing after halting the count operation with the START bit in RCR2 or using
a carry flag as shown in figure 13.2.
RHRCNT is not initialized by a power-on reset or manual reset, or in standby mode.
