NOTES:
1. MINIMUM PULSEWIDTH FOR HD AND VD IS 5 PIXEL CYCLES.
2. BOTH VD AND HD ARE INTERNALLY UPDATED AT SHP RISING EDGES. MINIMUM SET-UP TIME IS 3ns.
3. EVERY HD RISING EDGE WITH A PREVIOUS VD RISING EDGE WILL RESET TO 0101.
4. EVERY HD RISING EDGE WITHOUT A PREVIOUS VD RISING EDGE WILL ALTERNATE BETWEEN 0101... AND 2323.
