Output Format (0x00)
0
Bus Width
0: 24 bits: Data output on R_P, G_P, B_P only; R_S, G_S, B_S are all
driven low (default)
1: 48 bits: Data output on R_P, G_P, B_P, R_S, G_S, B_S
1
Interleaving
0: No interleaving: data changes on same edge of DATACLK
(48 bit mode only) (default)
1: Interleaved: Secondary databus data changes on
opposite edge of DATACLK from primary databus
2
Bus Swap
0: First data byte after trailing edge of HSOUT appears on
(48 bit mode only)
R_P, G_P, B_P (default)
1: First data byte after trailing edge of HSOUT appears on
R_S, G_S, B_S (primary and secondary busses are reversed)
3
Reserved
Set to 0.
4
422
0: Data is formatted as 4:4:4 (RGB, default)
(24 bit mode only) 1: Data is decimated to 4:2:2 (YUV), blue channel is driven
low
5

Polarity
0: HS_OUT, VS_OUT, and Pixel Data change on falling edge of
DATACLK (default)
1: HS_OUT, VS_OUT, and Pixel Data change on rising edge of
DATACLK
6
