7.1.2 White Shading Absolute Value Registers
The IIDC 1.31 specification defines White Shading as controlling three values, the red, green
and blue channel compensations, but only one absolute value register is defined for White
Shading. This does not allow for control of the separate channel compensations with
standard engineering units. So extra absolute value registers are defined as follows.
The offsets for the White_Shading absolute value CSRs are defined in the
ABS_CSR_HI_INQ_14 register (offset 738h). This will define the offsets for the red channel
compensation CSRs. The absolute value CSR offsets for the green and blue channels can
be calculated as follows : quadlet offset of green or blue CSRs = ABS_CSR_HI_ 3
*
X
(where X = 1 for green and X = 2 for blue).
