WAM - Bit 3 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.

TDM - Bit 2 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

WAF - Bit 1 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.

TDF - Bit 0 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.
