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 for day of the week can be set is 0 to 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.
RWKCNT is not initialized by a power-on reset or manual reset, or in standby mode.
