VEQWE[2:0] Source output delay period VEQWE[2:0] Source output delay period
3’h0 0 clocks (
*see Notes
) 3’h4 4 clocks
3’h1 1 clock 3’h5 5 clocks
3’h2 2 clocks 3’h6 6 clocks
3’h3 3 clocks 3’h7 7 clocks
Notes: 1. 1 clock
= (Number
of data transfer/pixel) x
DIVE
(division ratio) x
(PCDIVL + PCDIVH)) [DOTCLK]
2. The number of clocks is measured from the reference point. The reference point is the
alternating position of VCOM, which is set by SDTE bits.
