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.
