TOD. Three-State Output Drivers.
This bit allows the user to three-
state the output drivers: P[19:0], HS,
VS, FIELD, and SFL.

VBI_EN. Allows VBI data (Lines 1 to
21) to be passed through with only
a minimum amount of filtering
performed.
1 Only active video region

0 16 < Y < 235, 16 < C < 240 ITU-R BT.656 RANGE. Allows the user to select
the range of output values. Can be
BT656-compliant, or can fill the
whole accessible number range.
1 1 < Y < 254, 1 < C < 254 Extended range
0 SFL output is disabled EN_SFL_PIN
1 SFL information output on
the SFL pin
SFL output enables
encoder and decoder
to be connected
directly.
0 Decode and output color BL_C_VBI. Blank Chroma during
VBI. If set, enables data in the VBI
region to be passed through the
decoder undistorted.
