Description
YUV to RGB matrix bypass
0 = matrix enabled
1= matrix bypassed
Border color Y component for encoder operation mode. This value
is R in RGB mode
Border color U component for encoder operation mode. This value
is G in RGB mode
Border color V component for encoder operation mode. This value
is B in RGB mode
Parallel video input mode select
0 =30 bit parallel video input mode
1 =24 bit parallel video input mode
For details about which pins are used in 24 and 30-bit parallel
modes, please refer to section 2 table 5.
Always reads back ‘0’.
External/embedded trigger selection
0 = External VSYNC/O_E signal triggers the HD-SYNC generator
1 = D1 embedded O_E signal used to trigger the HD-SYNC
generator.
HD video data path enable
0 = Video demultiplexer bypassed for incoming 24/30-bit full parallel
video streams (DEMUX_MODE settings ignored)
1 = Video demultiplexer enabled for HD signals (DEMUX_MODE
settings apply)
Video DAC sleep mode powers off all analog circuitry but the band
gap reference.
primary video channel: DAC1-4
secondary video channel: DAC5-6
Power down mode for DACs; powers all analog circuitry
primary video channel: DAC1-4
secondary video channel: DAC5-6
