Bit 21 – HXSCBICU Horizontal Scaler Bicubic Coefficients Selected for Chroma Component

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

Bit 20 – HXSCTAP2 Horizontal Scaler Predefined Bilinear 2 Taps Selected for Chroma Component

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

Bits 17:16 – HXSCCFG[1:0] Horizontal Scaler Chroma/GB Configuration

Filter taps shift for chroma components. The value is from 0 to 3 when HXSYTAP2 = 0 (4 coefficients used) and from 0 to 1 when when HXSYTAP2 = 1 (2 coefficients used).

When using packed formats, HXSCCFG and HXSYCFG must have the same value.

Bit 5 – HXSYBICU Horizontal Scaler Predefined Bicubic Taps Selected for Luma/AR Component

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

Bit 4 – HXSYTAP2 Horizontal 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 – HXSYCFG[1:0] Horizontal Scaler Luma Configuration

Filter taps shift for luma component. The value is from 0 to 3 when HXSYTAP2 = 0 (4 coefficients used) and from 0 to 1 when when HXSYTAP2 = 1 (2 coefficients used).

When using packed formats, HXSCCFG and HXSYCFG must have the same value.
