OF0H/OF0M/OF0L (Primary ADC Offset Calibration Registers
*)
These three 8-bit registers hold the 24-bit offset calibration coefficient for the Primary ADC. These registers are configured at power-
on with a factory default value of 800000Hex. However, these bytes will be automatically overwritten if an internal or system zero-scale
calibration is initiated by the user via MD2–0 bits in the ADCMODE register.

OF1H/OF1L (Auxiliary ADC Offset Calibration Registers
*)
These two 8-bit registers hold the 16-bit offset calibration coefficient for the Auxiliary ADC. These registers are configured at power-on
with a factory default value of 8000Hex. However, these bytes will be automatically overwritten if an internal or system zero-scale
calibration is initiated by the user via the MD2–0 bits in the ADCMODE register.

Both Registers
GN0H/GN0M/GN0L (Primary ADC Gain Calibration Registers
*)
These three 8-bit registers hold the 24-bit gain calibration coefficient for the Primary ADC. These registers are configured at power-on
with a factory-calculated internal full-scale calibration coefficient. Every device will have an individual coefficient. However, these
bytes will be automatically overwritten if an internal or system full-scale calibration is initiated by the user via MD2–0 bits in the
ADCMODE register.

Power-On Default Value
Configured at factory final test, see notes above.

No
All Three Registers
GN1H/GN1L (Auxiliary ADC Gain Calibration Registers
*)
These two 8-bit registers hold the 16-bit gain calibration coefficient for the Auxiliary ADC. These registers are configured at power-on
with a factory calculated internal full-scale calibration coefficient. Every device will have an individual coefficient. However, these
bytes will be automatically overwritten if an internal or system full-scale calibration is initiated by the user via MD2–0 bits in the
ADCMODE register.

Power-On Default Value
Configured at factory final test, see notes above.
Bit Addressable

Both Registers
*These registers can be overwritten by user software only if Mode bits MD0–2 (ADCMODE SFR) are zero.
