* All of PWM DAC converters are centered with value 80h after power on.
6. H/V SYNC Processing
The H/V SYNC processing block performs the functions of composite signal separation/insertion, SYNC
inputs presence check, frequency counting, polarity detection and control, as well as the protection of
VBLANK output while VSYNC speed up in high DDC communication clock rate. The present and frequency
function block treat any pulse shorter than one OSC period as noise.
