15.3.5
The day of week counter (RWKCNT) is an 8-bit readable/writable register used for
setting/counting in the day of week section. The count operation is performed by a carry for each
day of the date counter.
The range for day of the week that can be set is 0 to 6 (decimal). Errant operation will result if any
other value is set. Carry out write processing after stopping the count operation with the START
bit in RCR2.
RWKCNT is not initialized by a power-on reset or manual reset, or in standby mode.
