I am using the rgb2dvi IP of digilent, and I wanted to know exactly how to use the pHSync, pVSync, and pVDE signals that it requires as an input
I can understand that pVDE is high for the duration of active video, and low for the duration on non-active video
For pHSync, is it high for the duration of the horizontal sync? Or does is it a single clock long? Does it go high on the same clock as pVDE goes low?
For pVsync, the same questions apply. Also, every end of a frame is also the end of a line, so do both pVSync and pHSync go high at the end of a frame?
Basically, my question is how these signals work together, and what they expect to be "fed"
