Bits 25:24 – VXSCCFG1[1:0] Vertical Scaler Chroma Configuration for Field 1(only used for YCrCb Interlaced Frame Content)

Filter taps shift for chroma components. The value is from 0 to 3 when VXSYTAP2 = 0 (4 coefficients used) and from 0 to 1 when when VXSYTAP2 = 1 (2 coefficients used).

Note: When using packed formats, VXSCCFG1 and VXSYCFG1 must have the same value.

Bit 22 – VXSCBICU Vertical Scaler Predefined Bicubic Taps Selected for Chroma/GB Component

Value	Description
0	Bicubic taps values are not selected.
1	Bicubic taps values are selected.

Bit 21 – VXSC1201N Vertical Scaler Bilinear 2 Taps Position among 4 Taps Filter for Chroma/GB Component

Value	Description
0	When selected, bilinear taps values are located on 0 and 1 positions (left aligned).
1	When selected, bilinear taps values are located on 0 and 1 positions (center aligned).

Bit 20 – VXSCTAP2 Vertical Scaler Predefined Bilinear 2 Taps Selected for Chroma/GB Component

Value	Description
0	Bilinear 2 taps value not selected.
1	Bilinear 2 taps value selected.

Bits 17:16 – VXSCCFG[1:0] Vertical Scaler Chroma/GB Configuration for Field 0 or Progressive Scan

Filter taps shift for chroma components. The value is from 0 to 3 when VXSYTAP2 = 0 (4 coefficients used) and from 0 to 1 when when VXSYTAP2 = 1 (2 coefficients used).

Note: When using packed formats, VXSCCFG and VXSYCFG must have the same value.

Bits 9:8 – VXSYCFG1[1:0] Vertical Scaler Chroma/GB Configuration for Field 1 (only used for interlaced frame content)

Filter taps shift for chroma components. The value is from 0 to 3 when VXSYTAP2 = 0 (4 coefficients used) and from 0 to 1 when when VXSYTAP2 = 1 (2 coefficients used).

Note: When using packed formats, VXSYCFG1 and VXSCCFG1 must have the same value.

Bit 6 – VXSYBICU Vertical Scaler Predefined Bicubic Taps Selected for Luma/AR Component

Value	Description

Value	Description
0	When selected, bilinear tap values are located on 0 and 1 positions (left-aligned).
1	When selected, bilinear tap values are located on 0 and 1 positions (center-aligned).

Bit 4 – VXSYTAP2 Vertical Scaler Predefined Bilinear 2 Taps Selected for Luma/AR Component

Value	Description
0	Bilinear 2 taps value not selected.
1	Bilinear 2 taps value selected.

Bits 1:0 – VXSYCFG[1:0] Vertical Scaler Luma/AR Configuration for Field 0 or Progressive Scan

Filter taps shift for luma component. The value is from 0 to 3 when VXSYTAP2=0 (4 coefficients used) and from 0 to 1 when VXSYTAP2=1 (2 coefficients used).

Note: When using packed formats, VXSYCFG and VXSCCFG must have the same value.
