bit 7-0 ARPT<7:0>: Alarm Repeat Counter Value bits
(2)
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.
REGISTER 25-2: RTCALRM: REAL-TIME CLOCK ALARM CONTROL REGISTER (CONTINUED)
Note 1: Hardware clears the ALRMEN bit anytime the alarm event occurs, when ARPT<7:0> = 00 and
CHIME = 0.
2: This field should not be written when the RTCC ON bit = ‘1’ (RTCCON<15>) and ALRMSYNC = 1.
Note: This register is reset only on a Power-on Reset (POR).
