OF_SEL [3:0]. Allows the user to choose from
a set of output formats.
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.
