M-5. H-clamp Pulse Generator
If the P14SF bit is set in the newly added SFR CONTREG4 (bit-addressable), the output pin P1.4 can
be used as the H-clamp pulse output (refer to Figure 13). The Hsync trigger type can be selected to
generate the H-clamp output pulse, and the pulse width of the H-clamp output can be determined by
programming the bits HCES, HCWS1, and HCWS2 in SFR CONTREG1. For details, see the
following figure and description.
