OFFSET of each channel is adjusted in 9-bit resolution.
Its center value is 0FFH and it is adjusted in 1/4 LSB per single step.
OFFSET adjust is valid only when black loop is disable ( LOOP MODE = 1 ).
Data Write of MSB bits does not affect the operation and Data value becomes valid
when Data write of LSB bits is made.

Black Loop setting values
[0], [7:0]
At minimum clamp level setting
(CLP LVL = 0)
At center clamp level setting
