Caution Bit 5 (WH20) of ALARMWH indicates AM(0)/PM(1) if AMPM = 0 (if the 12-hour system is selected).
This register is used to set minutes of alarm.
ALARMWM can be set by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
This register is used to set hours of alarm.
ALARMWH 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.
This register is used to set date of alarm.
ALARMWW can be set by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Set a decimal value of 00 to 59 to this register in BCD code. If a value outside the range is set,
the alarm is not detected.
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 the range is set, the alarm is not detected.
After reset: 00H
