RMINCNT is not initialized by a power-on reset or manual reset, or in standby mode.
12.2.4
The hour counter (RHRCNT) is an 8-bit read/write 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
perform a write using the carry flag as shown in figure 12.2.
RHRCNT is not initialized by a power-on reset or manual reset, or in standby mode.
12.2.5
The day of the week counter (RWKCNT) is an 8-bit read/write register used for setting/counting
in the BCD-coded day of week section of the RTC. The count operation is performed by a carry
for each day of the date counter.
The range that can be set is 0–6 (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
perform a write using the carry flag as shown in figure 12.2.
RWKCNT is not initialized by a power-on reset or manual reset, or in standby mode.
