) In the pulse mode, the increment of the second counter is delayed by approximately 92μs from the falling edge of clock pulses. Consequently, time
readings immediately after the falling edge of clock pulses may appear to lag behind the time counts of the real-time clocks by approximately 1 second.
Rewriting the second counter will reset the other time counters of less than 1 second, driving the INTR pin low.
