WEEK
Caution The value corresponding to the month count register (MONTH) or the day count register (DAY) is
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.
The WEEK register can be set by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
not stored in the week count register (WEEK) automatically. After reset release, set the week
count register as follow.
