WEEK
Caution Values corresponding to the month count register and day count register are not
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.
WEEK can be set by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
automatically stored to the week count register.
Be sure to set the week count register as follows, after reset release.
