WIE
Watchdog Interrupt Enable. When set to 1 and a watchdog time-out occurs, the
watchdog timer drives the INT pin as well as setting the WDF flag. When set to 0, the
watchdog time-out only sets the WDF flag.
AIE
Alarm Interrupt Enable. When set to 1, the alarm match drives the INT pin as well as
setting the AF flag. When set to 0, the alarm match only sets the AF flag.
PFIE
Power-Fail Enable. When set to 1, a power failure drives the INT pin as well as setting
the PF flag. When set to 0, a power failure only sets the PF flag.

H/L
High/Low. When set to a 1, the INT pin is driven active high. When set to 0, the INT pin
is open drain, active low.
P/L
Pulse/Level. When set to a 1, the INT pin is driven active (determined by H/L) by an
interrupt source for approximately 200 ms. When set to a 0, the INT pin is driven to an
active level (as set by H/L) until the Flags register is read.

10s Alarm Date
Alarm Date
Contains the alarm value for the date of the month and the mask bit to select or
deselect the date value.
M
Match. Setting this bit to 0 causes the date value to be used in the alarm match. Setting
this bit to 1 causes the match circuit to ignore the date value.

Alarm Hours
Contains the alarm value for the hours and the mask bit to select or deselect the hours
value.
M
Match. Setting this bit to 0 causes the hours value to be used in the alarm match.
Setting this bit to 1 causes the match circuit to ignore the hours value.
