16.2.5
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 settable range is 0 to 6 in decimal. If other values are set, correct operation is not provided.
When modifying RWKCNT, check that the count operation has been halted with the START bit
in RCR2.
RWKCNT is not initialized by a power-on reset or manual reset, or in standby mode, and the
operation is continued.
Days of the week are coded as shown in table 16.3.
