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.
RANGE. Allows the user to select
the range of output values. Can be
BT656-compliant, or can fill the
whole accessible number range.
