APPENDIX A: GPO Programming
Examples
(Continued)
GPO Programming Example #3:
Generate a control signal which toggles during horizontal
blanking and alternates polarity each frame. This control
signal is used as the reversal signal.
Horizontal time (clocks/line) = 1300 dot clocks
Vertical period (lines/frame) = 850 lines
Control is active beginning at line 1 and remains active for
769 lines.
(Odd number programmed in Duration Register causes con-
trol signal to alternate polarity each frame)
GPO Vertical Start Register = 1
GPO Vertical Duration Register = 769d (301h)
Positive going pulse causes output to toggle. Edge occurs
20 output clocks after end of each line (1024/2 + 20 = 532).
Pulse duration is not critical since the output will be in toggle
mode. (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 start # because the GPO pixel count
begins 6 clocks prior to the output data.
GPO Horizontal Start Register = 538 (238h)
GPO Horizontal Duration Register = 10d (0Ah)
The control pulses are positive (bit [0] = 0) and the toggle
circuitry is enabled (bit1 [1] = 1).
GPO Control Register = 2
(For a second control signal of opposite polarity, program
another GPO Control Register with same count values with
GPO Control Register = 3.)
