I am wondering if it is possible to emulate a video port with the N2HET. Therefore N2HET would need to generate the following signals:
PCLK (pixel clock) ~ 20 MHz, basically a PWM, 50% duty cycle.
VOUT_D0 to VOUT_D7 (video parallel data, 8bit) value might change each PCLK.
HSNYC (reflecting a video line, occurs after 576 PCLK).
YSYNC (reflecting a video frame, occurs after 576 HSYNC).
All must be in sync with PCLK.
