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 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.
