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.
