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.
