Fig.17 Timing of power supplying to AC pin
Set horizontal synchronous signal edge* waveform timing to under
5ns and input to HOR pin.
Set only the side which set by B/F register waveform timing under
5ns and input to HOR pin.
*: Set front porch edge or back porch edge by B/F register (ad-

PRECAUTION FOR USE
In order to avoid noise and latch-up, connect a bypass capacitor
( 0.1µF) directly between the V

Timing of power supplying to AC pin
The internal circuit of M35074-XXXSP is reset when the
level of the auto clear input pin AC is "L". This pin in hysteresis
input with the pull-up resistor.
The timing about power supplying of AC pin is shown in Figure 15.
