APC Setpoint 0 (APCSET0)

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.
