Reserved - Unknown during read
SDRAM Selector - Read/Write
Writing to these two bits defines which SDCSn[3:0] pin is
used to access the video frame buffer in SDRAM:
00
01

SDCSn[3] is selected by default on hardware reset.
Blank Pixel Data - Read/Write
Writing BKPXD = ‘1’ forces the pixel data on the P[17:0]
pins to be 0x0 when the blanking signal on the BLANK pin
is ‘0’.
0 - Disable
1 - Enable
This allows the use of an inexpensive external DAC that
does not contain data blanking logic.
Double Vertical - Read/Write
Writing DVERT = ‘1’ forces the values of the defined bit-
fields in the VLinesTotal, VSyncStrtStop, VActiveStrtStop,
VBlankStrtStop, and
(2X programmed value) when used.
0 - Disable
1 - Enable
