When the APC is on, the eight-bit signed integer compensation value corresponding to the current temperature is taken from
the BIASLUT look-up table, added to the selected APCSET (0, 1, or 2) register and loaded into the V
If DAC Calibration mode is selected in OEMCAL0, a write to any one of the three APCSETn registers will cause the V
to be updated immediately. DAC Calibration mode disables the output of the BIASLUT lookup table, so the unmodified
APCSETn register value propagates directly to the DAC.

A valid OEM password is required for access to these registers. These registers are non-volatile and will be maintained through
power and reset cycles.
