Fig. 9 Example of the M35045-XXXSP peripheral circuit (M35045-XXXFP peripheral circuit is same as that of M35045-XXXSP)
Note for waveform timing of the horizontal sig-
nals to the HOR 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.}
