1) Pulse mode : Outputs 2Hz, 1Hz clock pulses. For relationships with counting up of seconds see the diagram
below.

) When 32.000kHz crystal is used,
In the 2Hz clock pulse mode, 0.496s clock pulses and 0.504s clock pulse are output alternately.
Duty cycle for 1Hz clock pulses becomes 50.4% (“L” duration is 0.496s while “H” duration is 0.504s).
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), time
with apparently approx. one second of delay from time of the real-time clock may be read when time is read in synchronization with the falling edge of
output.
