Legend:  
R = Readable bit  
W = Writable bit  
‘1’ = Bit is set  
U = Unimplemented bit, read as ‘0’  
‘0’ = Bit is cleared x = Bit is unknown  
-n = Value at POR  
bit 15  
ALRMEN: Alarm Enable bit  
1= Alarm is enabled (cleared automatically after an alarm event whenever ARPT<7:0> = 00h and  
CHIME = 0)  
0= Alarm is disabled  
bit 14  
CHIME: Chime Enable bit  
1= Chime is enabled; ARPT<7:0> bits are allowed to roll over from 00h to FFh  
0= Chime is disabled; ARPT<7:0> bits stop once they reach 00h  
bit 13-10  
AMASK<3:0>: Alarm Mask Configuration bits  
0000= Every half second  
0001= Every second  
0010= Every 10 seconds  
0011= Every minute  
0100= Every 10 minutes  
0101= Every hour  
0110= Once a day  
0111= Once a week  
1000= Once a month  
1001= Once a year (except when configured for February 29th, once every 4 years)  
101x= Reserved; do not use  
11xx= Reserved; do not use  
bit 9-8  
ALRMPTR<1:0>: Alarm Value Register Window Pointer bits  
Points to the corresponding Alarm Value registers when reading the ALRMVALH and ALRMVALL registers.  
The ALRMPTR<1:0> value decrements on every read or write of ALRMVALH until it reaches ‘00’.  
ALRMVAL<15:8>:  
00= ALRMMIN  
01= ALRMWD  
10= ALRMMNTH  
11= Unimplemented  
ALRMVAL<7:0>:  
00= ALRMSEC  
01= ALRMHR  
10= ALRMDAY  
11= Unimplemented  
bit 7-0  
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; it is prevented from rolling over from 00h to FFh unless  
CHIME = 1.
