CAUTION: Changes to I2CADR take effect immediately! Any accesses following a write to I2CADR must be to the newly
programmed serial bus address. 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.

Default Value
Serial Address
Bytes Address
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 V
