B. Pin configurations
• Generate Falling Edge – generate a falling edge on the external G PO port if the present state of the output is high. If the
present state of the external GP O is low, no edge will be generated.
• Generate Rising Edge – generate a rising edge on the ex ternal GP O p ort if the present s tate of the output is low. If the present
state of the ex ternal GP O is high, no edge will be gene rated.
• Generate Toggle – ge nerate a toggle on the external GPO port. If the present state of the ou tput is low, a rising edge will be
generated, followed by a falling edge. If the presen t state of the output is high, a falling edge w ill be generated, followed by a
rising edge. The rate of toggle will be the vertical sync ra te (edge transition at each vsync). Pulse width = 20 millisecond s.
• Generate Continuous Toggle - This comm and will generate a continuous toggle of the external GPO por t. This toggle will
continue u ntil a Generate Falling Edge, Generate Rising Edge,orG enerate Toggle com mand is receiv ed.
The rate of toggle is
24Hz. .
