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.

Bit
Description
15
Current Channel ADC Enable.
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.
14 to 13
Current Source Enable.
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+.
12 to 10
Not Used. Reserved for future functionality and should be written as 0.
9
Current Channel ADC Output Coding.
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.
8
Not Used. Reserved for future functionality and should be written as 0.
7 to 6
Current Channel ADC Input Select.
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.
5 to 4
Current Channel ADC Reference Select.
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.
3 to 0
Current Channel ADC Gain Select. (Note that nominal I-ADC full-scale input voltage = VREF/GAIN.)
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.
