NOTES
1. BOTH VD AND HD ARE INTERNALLY UPDATED AT SHP RISING EDGES.
2. EVERY HD RISING EDGE WITH A PREVIOUS VD FALLING EDGE WILL RESET TO 0101.
3. EVERY HD RISING EDGE WITH A PREVIOUS VD RISING EDGE WILL RESET TO 2323.
4. EVERY HD RISING EDGE WITHOUT A PREVIOUS VD RISING EDGE WILL REPEAT EITHER 0101... (EVEN) OR 2323... (ODD).
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 SETUP TIME IS 3 ns.
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 1212.
