DISP Output Timing Adjustment
000: Adjustment of output timing is not
performed.
The DISP signal is output at the rising edge
of the dot clock, with the reference timing.
001: The DISP signal is output at the rising
edge, delayed one dot clock cycle relative
to the reference timing.
010: The DISP signal is output at the rising
edge, delayed two dot clock cycles relative
to the reference timing.
011: The DISP signal is output at the rising
edge, delayed three dot clock cycles
relative to the reference timing.
100: The DISP signal is output at the falling
edge, preceding the reference timing by 1/2
dot clock cycle.
101: The DISP signal is output at the falling
edge, delayed 1/2 dot clock cycle relative
to the reference timing.
110: The DISP signal is output at the falling
edge, delayed (1+1/2) dot clock cycles
relative to the reference timing.
111: The DISP signal is output at the falling
edge, delayed (2+1/2) dot clock cycles
relative to the reference timing.
