Function
Contains a 24-bit word which is the offset calibration
coefficient for the part. The contents of this register
are used to provide offset correction on the output
from the digital filter. There are five Offset Registers
on the part and these are associated with input chan-
nels as outlined in the ADCCON register.
Contains a 24-bit word which is the gain calibration
coefficient for the part. The contents of this register
are used to provide gain correction on the output
from the digital filter. There are five Gain Registers
on the part and these are associated with input chan-
nels as outlined in the ADCCON register.
Contains a 16-bit word which is the offset calibration
coefficient for the part. The contents of this register
are used to provide offset correction on the output
from the digital filter. There are five Offset Registers
on the part and these are associated with input chan-
nels as outlined in the ADCCON register.
