Description

SEL_PIX

DCVBS Output Selection.

When SEL_PIX is HIGH, the interpolated pixel data is selected as the

output for the DCVBS port. When SEL_PIX is LOW, the non-interpolated

pixel data is selected as the output for the DCVBS port.

RGB_CLIP

RGB Limit Control.

When RGB_CLIP is LOW, the RGB outputs are not limited.

When RGB_CLIP is HIGH, the RGB outputs are limited to a range of 256 to

1023 at the DAC outputs.

GAUSS_BYP

Gaussian Bypass Select.

When GAUSS_BYP is LOW, the gaussian filter is enabled.

When GAUSS_BYP is HIGH, the gaussian filter is bypassed.

SEL_CLK

DCVBS Clock Select.

When SEL_CLK is LOW, the DCVBS output is clocked at the PXCK.

When SEL_CLK is HIGH, the DCVBS output is clocked at the PCK.

C2DB_OFF

COMP2DB Offset Selection.

When C2DB_OFF is HIGH an offset of 256 is added to the COMP2 output

allowing the chrominance data that extends below the sync level to be

passed through the outputs.

NMEH

NTSC-M Component Enhancement.

When NMEH is LOW, the CSM performs the normal rounding operation on

multipliers 8, 9 , and 10. When NMEH is HIGH, the CSM extends the

number of rounding bits on multipliers 8, 9, and 10. This is recommended if

the input source is YCBCR and the component output is RGB.
