2) Level mode : One second, one minute or one month may be selected for an interrupt cycle. Counting up of sec-
onds is matched with falling edge of interrupt output.
3) When the time trimming circuit is used, periodic interrupt cycle changes every 20 seconds.
Pulse mode : “L” duration of output pulses may change in the maximum range of ±3.784ms (±3.875ms when
32.000kHz crystal is used.)
For example, Duty will be 50±0.3784% (or 50±0.3875% when 32.000kHz crystal is used) at 1Hz.
Level mode : Frequency in one second may change in the maximum range of ±3.784ms (±3.875ms when
32.000kHz crystal is used.)

) Since counting up of seconds and the falling edge has a time lag of approx. 92μs (at 32.768kHz) (approx. 94μs when 32.000kHz crystal is used), a
time may be read with apparently approx. one second delayed from time of the real-time clock when time is read in synchronization with the falling
edge of output.
