When A.P.C. is on, i.e., the APCCAL bit in OEMCAL0 is set, the value in APCSETx is added to the signed value taken from the
A.P.C. look-up table and loaded into the VBIAS DAC. When A.P.C. is off, the value in APCSET is loaded directly into the VBIAS
DAC, bypassing the look-up table entirely. In either case, the VBIAS DAC setting is reported in the VBIAS register. The
APCCFG bits determine the DAC’s response to higher or lower numeric values. A valid OEM password is required for access to
this register. This register is non-volatile and will be maintained through power and reset cycles.

When A.P.C. is on, the value corresponding to the current temperature is taken from the MODLUT look-up table, added to
MODSET and loaded into the VMOD DAC. This register is non-volatile and will be maintained through power and reset cycles. A
valid OEM password is required for access to this register.
