The video interface consists of a bidirectional, tri-stateable 5-wire data bus. The nibble transmission is synchronised to the rising
edge of the system clock (Figure 31).
Digital video data may be either 8 or 10 bits per sample, and can be transmitted in one of the following ways:
10-bit data
8-bit data
note: if the 8-wire output mode has been selected then the normal FST/LST pin function is sacrificed as these pins are required
to output data information
In the following description the 4-wire mode is used as an example. The 5-wire mode can be viewed as a variant of the 4-wire
mode. Data is output on the least significant data wires available. e.g. in 4-wire mode, data is output on data wires D[3:0] while in
1. A series pair of 5-bit nibbles, most significant nibble first, on 5 wires.
2. An 8-bit number e.g. line code. line numbers and status line data is padded with 00 in the least significant two bits to make
1. A single 8 bit byte over 8 output wires
2. A series pair of 4-bit nibbles, most significant nibble first, on 4 wires.
3. The top 8-bits of a 10-bit value e.g. pixel data or line averages is used as the 8-bit equivalent.
