(7) Minute count register (RC1MIN)
(8) Hour count register (RC1HOUR)
The RC1MIN register is an 8-bit register that takes a value of 0 to 59 (decimal) and indicates the count value of
minutes.
It counts up when the second 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.
Set a decimal value of 00 to 59 to this register in BCD code.
This register can be read or written 8-bit units.
Reset sets this register to 00H.
Caution Setting a value other than 00 to 59 to the RC1MIN register is prohibited.
Remark
The RC1HOUR register is an 8-bit register that takes a value of 0 to 23 or 1 to 12 (decimal) and indicates the count
value of hours.
It counts up when the minute 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.
Set a decimal value of 00 to 23, 01 to 12, or 21 to 32 to this register in BCD code.
This register can be read or written 8-bit units.
Reset sets this register to 12H.
However, the value of this register is 00H if the AMPM bit is set to 1 after reset.
Cautions 1. Bit 5 of the RC1HOUR register indicates a.m. (0) or p.m. (1) if AMPM = 0 (if the 12-hour
