The MONTH register is an 8-bit register that takes a value of 1 to 12 (decimal) and indicates the count value of
months.
It counts up when the day counter overflows.
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. Even if the day count register overflows while this register is being written, this register ignores the overflow
and is set to the value written. Set a decimal value of 01 to 12 to this register in BCD code. Set a decimal value of
01 to 12 to this register in BCD code.
MONTH can be set by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 01H.
The YEAR register is an 8-bit register that takes a value of 0 to 99 (decimal) and indicates the count value of years.
It counts up when the month counter overflows.
Values 00, 04, 08, …, 92, and 96 indicate a leap year.
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. Even if the month count register overflows while this register is being written, this register ignores the
overflow and is set to the value written. Set a decimal value of 00 to 99 to this register in BCD code. Set a decimal
value of 00 to 99 to this register in BCD code.
YEAR can be set by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
