Current Channel ADC Control Register
Name: ADC0CON
Address: 0xFFFF050C
Default Value: 0x00002
Access: Read/write
Function: The current channel ADC control MMR is a 16-bit register that is used to configure the I-ADC. Note that if the current ADC
is reconfigured via ADC0CON, the voltage and temperature ADCs are also reset.

Description
Current Channel ADC Enable.
Current Source Enable.
Not Used. Reserved for future functionality and should be written as 0.
Current Channel ADC Output Coding.
Not Used. Reserved for future functionality and should be written as 0.
Current Channel ADC Input Select.
Current Channel ADC Reference Select.
Current Channel ADC Gain Select. (Note that nominal I-ADC full-scale input voltage = VREF/GAIN.)
Set to 1 by user code to enable the I-ADC.
Cleared to 0 to power down the I-ADC and reset the respective ADC ready bit in the ADCSTA MMR to 0.
00 = current sources off.
01 = enable 50 μA current source on IIN+.
10 = enable 50 μA current source on IIN−.
11 = enable 50 μA current source on both IIN− and IIN+.
Set to 1 by user code to configure I-ADC output coding as unipolar.
Cleared to 0 by user code to configure I-ADC output coding as twos complement.
00 = internal, 1.2 V precision reference selected. In ADC low power mode, the voltage reference selection is controlled by
ADCMDE[5].
01 = external reference inputs (VREF, GND_SW) selected.
10 = external reference inputs divided by 2 ((VREF, GND_SW)/2) selected allows an external reference up to REG_AVDD.
11 = (REG_AVDD, AGND)/2 selected.
0000 = I-ADC gain = 1.
0001 = I-ADC gain = 2.
0010 = I-ADC gain = 4.
0011 = I-ADC gain = 8.
0100 = I-ADC gain = 16.
0101 = I-ADC gain = 32.
0110 = I-ADC gain = 64.
0111 = I-ADC gain = 128.
1000 = I-ADC gain = 256.
1001 = I-ADC gain = 512.
1xxx = I-ADC gain is undefined.
00 = IIN+, IIN−.
01 = IIN−, IIN−. Diagnostic, internal short configuration.
10 = ADC reference/136, 0 V. Diagnostic, test voltage for gain settings ≤ 128.
11 = not defined.
