1, 1, 0 ADC System Zero-Scale Calibration
In this mode, an zero-scale calibration is performed on enabled ADC channels against an external zero-scale voltage
driven at the ADC input pins. The calibration is carried out at the user programmed ADC settings, therefore, as with a
normal single ADC conversion, it will take 3 ADC conversion cycles before a fully settled calibration result is ready.
1, 1, 1 ADC System Full-Scale Calibration
In this mode, an full-scale calibration is performed on enabled ADC channels against an external full-scale voltage
driven at the ADC input pins.
Current Channel ADC Control Register :
Name :
ADC0CON
Address :
0xFFFF050C
Default Value :
0x0002
Access :
Read/Write
Function :
The Current Channel ADC Control MMR is an 16-bit register that is used to configure the I-ADC.
Note:
If the Current ADC is reconfigured via ADC0CON, the Voltage and Temperature ADCs are also reset.

Bit
Description
15
Current Channel ADC Enable
This bit is set to 1 by user code to enable the I-ADC
Clearing this bit to 0, powers down the I-ADC and resets the respective ADC READY bit in the ADCSTA MMR to 0
14, 13
IIN Current Source Enable
0, 0
Current Sources Off
0, 1
Enable 50uA current source on IIN+
1, 0
Enable 50uA current source on IIN-
1, 1
Enable 50uA current source on both IIN- and IIN+
NOTE: These current sources have a tolerance of +-30%. A PGA gain equal to or greater than 2 ( ADC0CON [3-0 ] != 0000 )
must be used when current sources are enabled.
12– 10
Not Used
These bits are reserved for future functionality and should be written as zero
9
Current Channel ADC Output Coding
This bit is set to 1 by user code to configure I-ADC output coding as unipolar
This bit is cleared to 0 by user code to configure I-ADC output coding as 2’s complement
8
Not Used
This bit is reserved for future functionality and should be written as zero
7, 6
Current Channel ADC Input Select
0, 0
IIN+, IIN-

Diagnostic, internal short configuration
1, 0
ADC Reference/136, 0V
Diagnostic, test voltage for gain settings <= 128
ADC Reference/(1.0625XGain), 0V
Diagnostic, test voltage for gain settings > 128
Note: If (REG_AVDD, AGND) divided by 2 Reference is selected, REG_AVDD is used for Vref in this mode. This will
lead to ADC0DAT scaled by two
1, 1
Not Defined
5, 4
Current Channel ADC Reference Select
0, 0
Internal, 1.2V precision reference selected. In ADC Low Power Mode, the Voltage Reference selection is
controlled by ADCMDE[5]
0, 1
External reference inputs (VREF, GND_SW) selected
1, 0
External reference inputs divided by 2 (VREF, GND_SW)/2 selected, this allows an external reference up to
REG_AVDD
1, 1
(REG_AVDD, AGND) divided by 2 selected
