Name
Description
ADCCON3.7 BUSY
The ADC Busy Status Bit (BUSY) is a read-only status bit that is set during a valid ADC conversion or
calibration cycle. Busy is automatically cleared by the core at the end of conversion or calibration.
ADCCON3.6 GNCLD
Gain Calibration Disable Bit
Set to “0” to Enable Gain Calibration.
Set to “1” to Disable Gain Calibration.
ADCCON3.5 AVGS1
Number of Averages Selection Bits
ADCCON3.4 AVGS0
This bit selects the number of ADC readings averaged during a calibration cycle.

ADCCON3.3 RSVD
Reserved. This bit should always be written as “0.”
ADCCON3.2 RSVD
This bit should always be written as “1” by the user when performing calibration.
ADCCON3.1 TYPICAL
Calibration Type Select Bit.
This bit selects between Offset (zero-scale) and gain (full-scale) calibration.
Set to 0 for Offset Calibration.
Set to 1 for Gain Calibration.
ADCCON3.0 SCAL
Start Calibration Cycle Bit.
When set, this bit starts the selected calibration cycle. It is automatically cleared when the calibration
cycle is completed.
ADCCON3 – (ADC Control SFR #3)
The ADCCON3 register controls the operation of various calibra-
tion modes as well as giving an indication of ADC busy status.
SFR Address:
F5H
SFR Power-On Default Value:
00H
Bit Addressable:
NO
