Bit 3: WAM (Watchdog Alarm Mask). When this bit is set to a logic 0, the Watchdog Interrupt output
will be activated. The activated state is determined by bits 1,4,5, and 6 of the Command Register. When
this bit is set to a logic 1, the Watchdog interrupt output is deactivated.
Bit 2: TDM (Time-of-Day Alarm Mask). When this bit is set to a logic 0, the Time of Day Alarm
Interrupt output will be activated. The activated state is determined by bits 0, 4, 5, and 6 of the Command
Register. When this bit is set to a logic 1, the Time of Day Alarm interrupt output is deactivated.
Bit 1: WAF (Watchdog Alarm Flag). This bit is set to a logic 1 when a watchdog alarm interrupt
occurs. This bit is read-only.
The bit is reset when any of the Watchdog Alarm registers are accessed.
When the interrupt is in the pulse mode (see bit 4 definition), this flag will be in the logic 1 state only
during the time the interrupt is active.
Bit 0: TDF (Time-of-Day Flag). This is a read-only bit. This bit is set to a logic 1 when a time of day
alarm has occurred. The time the alarm occurred can be determined by reading the Time of Day Alarm
registers. This bit is reset to a logic 0 state when any of the Time of Day Alarm registers is accessed.
When the interrupt is in the pulse mode (see bit 4 definition), this flag will be in the logic 1 state only
during the time the interrupt is active.
