The interface has an 8-bit data bus, transferring a single 8-bit value (Y/U/V) in each cycle. The timing of
the interface is described in

The frequency of the clock DISP_CLK is 27 MHz (within 10%)
The HSYNC, VSYNC signals are active low.
The DRDY signal is shown as active high.
The transition to the next row is marked by the negative edge of the
HSYNC signal. It remains low for a single clock cycle.
The transition to the next field/frame is marked by the negative edge of
the VSYNC signal. It remains low for at least one clock cycles.

of VSYNC and HSYNC coincide.

coincide.
The active intervals—during which data is transferred—are marked by
the HSYNC signal being high.
At a transition to an odd field (of the next frame), the negative edges
At a transition is to an even field (of the same frame), they do not
