Description
0
Soft Power Down; 0 = Power Down, 1 = Normal Operation
1
Reserved
2
BPASS (1 = bypass, 0 = non-bypass)
This field is valid only when DUAL pin is 0V or 1⁄2VCC. Note: When image scaling is not required power savings
can be achieved in bypass mode.
3
DSEL
0= Input clock is differential (recommended for clocks above 65 MHz),
1= input clock is single-ended
4
HEN (HSYNC enable)
0= HSYNC is transmitted as a fixed low,
1= HSYNC is same as input
5
