Unused Bits 31 : 27
RGB_SYNC Bits 26 : 24
R/W
0x0
R, G and B signals sync embedding selection.
These bits specify whether the sync signal is added to each of the R, G and B
components (b 1 ) or not (b‘0’).
The bit[26] specify if the R signal has
embedded syncs, the bit[25] specify if the G signal has embedded syncs and
the bit[24] specify if the B signal has embedded syncs. When comp_yuv is
equal to b 1 , these bits are N.A. and should be set to b'000'.
When the value is different from b'000', RGB_SETUP should be set to b 1 .

RGB_SETUP Bit 16
R/W
0x0
Set-up enable for RGB outputs.
This bit specifies if the set-up implied value (black_level - blank_level)
specified for the CVBS signal is used also for the RGB signals.
0: The set-up is not used, or i.e. comp_yuv is equal to b 1 .
1: The implied set-up is used for the RGB signals
Unused Bits 15 : 1
BYPASS_YCLAMP Bit 0
R/W
0x1
Y input clamping selection
This bit selects whether the Video Encoder Y input is clamped to 64 to 940
or not. When not clamped the expected range is 0 to 1023. The U and V
inputs are always clamped to the range 64 to 960.
0: The Video Encoder Y input is clamped
1: The Video Encoder Y input is not clamped
