These are the constant registers. Derived from the D3DRS_TEXTUREFACTOR constant, the constant factor registers are loaded by the application through the Direct3DDevice8.SetPixelShaderConstant method.
The constant factor registers are read-only. There are at least eight constant factor registers defined for use by a pixel shader, but a maximum of two may be used in any one instruction.
