In the single mode each line consists of 12 empty pixels (E1 – E12),
followed by 24 masked pixels used for black reference (R1 – R24),
followed by 4 buffer pixels (B1 – B4), followed by 640 active data
pixels (D1 – D640), followed by 4 buffer pixels (B1 – B4), and
followed by another 24 masked dark pixels (R1 – R24) – Figure 2.3. In
dual mode each line consists of 12 empty pixels (E1 – E12), followed
by 24 masked pixels used for black reference (R1 – R24), followed by
4 buffer pixels (B1 – B4), followed by 320 active data pixels – Figure
2.4. The data is sampled on the rising edge of the clock, and the LVAL
(line valid) signal is active only during the active pixels. Each frame
(for all modes) consists of 35.4 us vertical frame timing, followed by 4
masked dark lines (RL1 – RL4), followed by 4 buffer lines (B1 – B4),
followed by 480 active lines (L1 – L480), and followed by 4 buffer
lines (B1 – B4). During each frame the FVAL (frame valid) signal is
active only during the a
