EXAMPLE OF THE M35045-XXXSP/FP CLOCK PERIPHERAL CIRCUIT
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.
Horizontal synchronous signal input
: Set front porch edge or back porch edge by B/F register.
