Chapter 6 Register Set
6.5.40 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 Register 38h: R_COMP_OFF
The R_COMP_OFF Register is used to adjust as necessary the comparator offset for the red ‘B’ and ‘A’
channels.
