I want to use the dm6437 video output formatter when processing a raw image. The documentation for setting up the registers is a little fuzzy to me. If I want x lines written to SRAM after the video data formatter, what values do I need to use for these registers? I can adjust the number of lines output by the camera to whatever I want. Also, since the output has to be at least 1 line less than the input, which line(s) are eaten by the output formatter? First or last?
FMT_VERT
VP_OUT
VERT_LINES
VERT_START
I figured I would set up the camera to output x + 2 lines (since it is raw bayer the length has to be even). What are my other register values (relating to the height)?
