REGISTER 20-2: RTCALRM: RTC ALARM CONTROL REGISTER(1) (CONTINUED)

bit 7-0 ARPT<7:0>: Alarm Repeat Counter Value bits(3)

11111111 = Alarm will trigger 256 times

•

•

•

00000000 = Alarm will trigger one time

The counter decrements on any alarm event. The counter only rolls over from 0x00 to 0xFF if CHIME = 1.

Note 1:

2:

3:

4:

This register is reset only on a Power-on Reset (POR).

Hardware clears the ALRMEN bit anytime the alarm event occurs, when ARPT<7:0> = 00 and

CHIME = 0.

This field should not be written when the RTCC ON bit = ‘1’ (RTCCON<15>) and ALRMSYNC = 1.

This assumes a CPU read will execute in less than 32 PBCLKs.
