Calibration Registers

The registers in this section can be used to calibrate the ICS1531. Typically, the Calibration registers do not

need to be adjusted. However, access is provided so that production-line calibrations can be made as

necessary.

Note:

For information on how to enable the Calibration Regs, see Reg 37:3.

6.5.40.1

The R_COMP_OFF Register is used to adjust as necessary the comparator offset for the red ‘B’ and ‘A’

channels.

6.5.40.2

The G_COMP_OFF Register is used to adjust as necessary the comparator offset for the green ‘B’ and ‘A’

channels.

6.5.40.3

The B_COMP_OFF Register i is used to adjust as necessary the comparator offset for the blue ‘B’ and ‘A’

channels.
