Function
Operation
D0
Software Reset (0 = Normal Operation, 1 = Reset all registers to default)
D2, D1
Power-Down Modes (00 = Normal Power, 01 = Standby, 10 = Total Shutdown)
D3
OB Clamp Disable (0 = Clamp ON, 1 = Clamp OFF)
D5, D4
Test Mode. Should always be set to 00.
D6
PBLK Blanking Level (0 = Blank Output to Zero, 1 = Blank to OB Clamp Level)

D11 to D0
Required start-up write must be set to 0x838.
NOTE: All register values default to 0x0000 at power-up except clamp level, which defaults to 128 decimal (128 LSB clamp level).
Low Gain Mode. Normally set to 00. To enable low gain mode, set to 11. When low gain mode
is enabled, VGA Gain register must be set to all zeroes.
Test Mode. Should always be set to 000.
