FUNCTIONAL DESCRIPTION

Motor Output Waveform

Watch movement period Tcy = 2s, Pulsewidth Tpw = 3.9ms

Reset Function

Reset operation

The device reset condition occurs when the RESET pin goes HIGH (VDD), and the circuits are reset in 4Hz fre-

quency divider steps. Note, however, that RESET must stay HIGH for 93.7ms or longer, otherwise the reset

input is ignored.

Reset release operation

If the last pulse before reset was output on OUT1, then the ﬁrst pulse after reset is released is output on OUT2,

and vice versa. The time interval, TD, after reset is released until the ﬁrst pulse output occurs is TCY/2 − 0.125s

to TCY/2.
