ALRMEN: Alarm Enable bit
1 = Alarm is enabled (cleared automatically after an alarm event whenever ARPT<7:0> = 0x00 and
0 = Alarm is disabled
CHIME: Chime Enable bit
1 = Chime is enabled; ARPT<7:0> bits are allowed to roll over from 0x00 to 0xFF
0 = Chime is disabled; ARPT<7:0> bits stop once they reach 0x00
AMASK<3:0>: Alarm Mask Configuration bits
11xx = Reserved – do not use
101x = Reserved – do not use
1001 = Once a year (except when configured for February 29th, once every 4 years)
1000 = Once a month
0111 = Once a week
0110 = Once a day
0101 = Every hour
0100 = Every 10 minutes
0011 = Every minute
0010 = Every 10 seconds
0001 = Every second
0000 = Every half second
ALRMPTR<1:0>: Alarm Value Register Window Pointer bits
Points to the corresponding Alarm Value registers when reading ALRMVALH and ALRMVALL registers;
the ALRMPTR<1:0> value decrements on every read or write of ALRMVALH until it reaches ‘00’.

11 = Unimplemented
10 = ALRMMNTH
01 = ALRMWD

11 = Unimplemented
10 = ALRMDAY
01 = ALRMHR
00 = ALRMSEC
ARPT<7:0>: Alarm Repeat Counter Value bits
11111111 = Alarm will repeat 255 more times

•
00000000 = Alarm will not repeat
The counter decrements on any alarm event. The counter is prevented from rolling over from 0x00 to
0xFF unless CHIME = 1.
