0: All three D-to-A converters are set for 6-bit operation. This is the default after reset.
1: All three D-to-A converters are set for 8-bit operation.
This bit always returns the value of 0 when read.
Pixel averaging causes the red, green and blue color component values of a replicated
pixel created by the horizontal stretching process to be averaged with those of the next
pixel.
0: Disables pixel averaging. This is the default after reset.
1: Enables pixel averaging.
Note: The pixel averaging feature applies only to flat panel displays, not CRT’s, and it
applies only when horizontal stretching is active (see the description of the Horizontal
Stretching Register, FR41, for more details).
