Caution The value corresponding to the month count register or the day count register is not stored
The WEEK register is an 8-bit register that takes a value of 0 to 6 (decimal) and indicates the count value of
weekdays.
It counts up in synchronization with the day counter.
When data is written to this register, it is written to a buffer and then to the counter up to 2 clocks (32.768 kHz)
later. Set a decimal value of 00 to 06 to this register in BCD code. If a value outside the range is set, the
register value returns to the normal value after 1 period.
WEEK can be set by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
in the week count register automatically. After reset release, set the week count register as
follow.
