MIN
The MIN 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. If a value outside this range is set, the
register value returns to the normal value after 1 period.
MIN can be set by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
The HOUR register is an 8-bit register that takes a value of 00 to 23 or 01 to 12, 21 to 32 (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. If a value outside this
range is set, the register value returns to the normal value after 1 period.
HOUR can be set by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 12H.
However, the value of this register is 00H if the AMPM bit (bit 3 of the RTCC0 register) is set to 1 after reset.
Caution Bit 5 (HOUR20) of HOUR indicates AM(0)/PM(1) if AMPM = 0 (if the 12-hour system is
selected).
After reset: 00H
After reset: 12H
