Function
Provides the most up-to-date conversion result from
the main ADC. Main ADC data register length
can be programmed to be 16-bit or 24-bit.
Provides the most up-to-date conversion result from
the auxiliary ADC. Aux ADC data register length is
16 bits.
Contains a 24-bit word that 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 three offset registers
on the part and these are associated with input channel
pairs as outlined in the AD0CON register.
Contains a 24-bit word that 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 three Gain registers
on the part, which are associated with input channel
pairs as outlined in the AD0CON register.
Contains a 16-bit word that 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.
Contains a 16-bit word that 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.
Contains an 8-bit byte that is the identifier for the part.
Controls the test modes of the part, which are used
when testing the part. The user is advised not to
change the contents of these registers.
