ADC Status Register. Holds the general status of the primary and auxiliary (ADuC845 only) ADCs.
ADC Mode Register. Controls the general modes of operation for primary and auxiliary (ADuC845 only) ADCs.
Primary ADC Control Register 1. Controls the specific configuration of the primary ADC.
Primary ADC Control Register 2. Controls the specific configuration of the primary ADC.
Auxiliary ADC Control Register. Controls the specific configuration of the auxiliary ADC. ADuC845 only.
Primary ADC 24-bit gain calibration coefficient is held in these three 8-bit registers. GN0L is not available on the ADuC848.
Auxiliary ADC 16-bit gain calibration coefficient is held in these two 8-bit registers. ADuC845 only.
Description
Sinc Filter Register. Configures the decimation factor for the Sinc
only) ADC update rates.
Current Source Control Register. Allows user control of the various on-chip current source options.
Primary ADC 24-bit (16-bit on the ADuC848) conversion result is held in these three 8-bit registers. ADC0L is not available on
the ADuC848.
Auxiliary ADC 24-bit conversion result is held in these two 8-bit registers. ADuC845 only.
Primary ADC 24-bit offset calibration coefficient is held in these three 8-bit registers. OF0L is not available on the ADuC848.
Auxiliary ADC 16-bit offset calibration coefficient is held in these two 8-bit registers. ADuC845 only.
