Color Output Swap (MR53)
By default, DAC B is configured as the Pr output and DAC
C as the Pb output. In setting this bit to “1” the DAC out-
puts can be swapped around so that DAC B outputs Pb and
DAC C outputs Pr. Table III demonstrates this in more detail.
This control is also available in RGB mode.

Gamma Curve (MR54)
This bit selects which of the two programmable gamma curves
is to be used. When setting MR54 to “0,” the gamma correction
curve selected is Curve A. Otherwise Curve B is selected. Each
curve will have to be programmed by the user as explained in
the Gamma Correction Registers section.
Gamma Correction (MR55)
To enable Gamma Correction, and therefore activate the gamma
curve programmed by the user, this bit must be set to “1.” Other-
wise the programmable Gamma Correction facility is bypassed.
Programming of the gamma correction curves is explained in
the Gamma Correction Registers section.
Adaptive Mode Control (MR56)
For this control to be effective, Adaptive Filter Control must be
enabled (MR57 = “1”) as well as the Sharpness Filter (MR17 =
“1”). For filter plots, refer to Sharpness Filter Control and
Adaptive Filter Control section.
Adaptive Filter Control (MR57)
This bit enables the Adaptive Filter Control when set to “1.”
Sharpness Filter must be enabled as well (MR17 = “1”). The
Adaptive Filter Controls is explained in more detail under
Sharpness Filter Control and Adaptive Filter Control section.

These three 8-bit-wide registers are used to program the output
color of the internal test pattern generator, be it the lines of the
cross-hatch pattern or the uniform field test pattern and are
available in PS mode and HDTV mode.
The standard used for the values for Y and the color difference
signals to obtain white, black and the saturated primary and
complementary colors conforms to the ITU-R BT 601-4 standard.
