APPENDIX A: GPO Programming
Examples
(Continued)
GPO Programming Example #2:
Generate a control signal which transitions low 20 output
clocks after the beginning of each output line, has a pulse-
width (low) of 12 μs, and goes high during horizontal blank-
ing. This control signal is used as an output enable for the
gate drivers.
Horizontal time (clocks/line) = 1300 dot clocks
Vertical period (lines/frame) = 850 lines
Control is active beginning at line 2 and remains active for
768 lines.
GPO Vertical Start Register = 2
GPO Vertical Duration Register = 768d (300h)
Negative pulse goes low each line at output clock 20 corre-
sponding to when the 39/40 pixels are output on OR, OG,
OB, ER, EG, EB. Pulse remains low for 390 output clocks
(390 x 30.8 ns/clock = 12 μs). (Dual Bus output clock =
32.5 MHz for 65 MHz XGA video, 1024 pixels/line, 768
lines/frame).
Note:
6 counts are added to the output clock # because the GPO start count
begins 6 clocks prior to the output data.
GPO Horizontal Start Register = 26d (1ah)
GPO Horizontal Duration Register = 390d (186h)
The control pulses are negative (bit [0] = 1) and the toggle
circuitry is disabled (bit1 [1] = 0).
GPO Control Register = 1
