(11) Month count register (RC1MONTH)
The RC1MONTH 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 (2 x 32.768 kHz)
later. Set a decimal value of 01 to 12 to this register in BCD code.
This register can be read or written in 8-bit units.
Reset sets this register to 01H.
Caution Setting a value other than 01 to 12 to the RC1MONTH register is prohibited.
Remark See 12.4.1 Initial settings, 12.4.2 Rewriting each counter during the real-time counter operation,
and 12.4.3 Reading each counter during the real-time counter operation when reading or writing
the RC1MONTH register.

(12) Year count register (RC1YEAR)
The RC1YEAR 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 (2 x 32.768 kHz)
later. Set a decimal value of 00 to 99 to this register in BCD code.
This register can be read or written in 8-bit units.
Reset sets this register to 00H.
Caution Setting a value other than 00 to 99 to the RC1YEAR register is prohibited.
Remark See 12.4.1 Initial settings, 12.4.2 Rewriting each counter during the real-time counter operation,
and 12.4.3 Reading each counter during the real-time counter operation when reading or writing
the RC1YEAR register.
