NOTES
1. VD FALLING EDGE WILL RESET THE PxGA GAIN REGISTER STEERING TO 0101 LINE.
2. HD FALLING EDGES WILL ALTERNATE THE PxGA GAIN REGISTER STEERING BETWEEN 0101 AND 2323 LINES.
3. FIELDVAL IS ALWAYS RESET TO 0 ON VD FALLING EDGES.
NOTES
1. FIELDVAL = 0 (START OF FIRST FIELD) WILL RESET THE PxGA GAIN REGISTER STEERING TO 0101 LINE.
2. FIELDVAL = 1 (START OF SECOND FIELD) WILL RESET THE PxGA GAIN REGISTER STEERING TO 2323 LINE.
3. HD FALLING EDGES WILL RESET THE PxGA GAIN REGISTER STEERING TO EITHER 0 (FIELDVAL = 0) OR 2 (FIELDVAL = 1).
4. FIELDVAL WILL TOGGLE BETWEEN 0 AND 1 ON EACH VD FALLING EDGE.
NOTES
1. FIELDVAL = 0 (START OF FIRST FIELD) WILL RESET THE PxGA GAIN REGISTER STEERING TO 0101 LINE.
2. FIELDVAL = 1 (START OF SECOND FIELD) WILL RESET THE PxGA GAIN REGISTER STEERING TO 2323 LINE.
2. FIELDVAL = 2 (START OF THIRD FIELD) WILL RESET THE PxGA GAIN REGISTER STEERING TO 0101 LINE.
3. HD FALLING EDGES WILL ALTERNATE THE PxGA GAIN REGISTER STEERING BETWEEN 0101 AND 2323 LINES.
4. FIELDVAL WILL INCREMENT AT EACH VD FALLING EDGE, REPEATING THE 0...1...2...0...1...2 PATTERN.
