The current channel ADC control MMR is a 16-bit register that is used to configure the I-ADC.
If the current ADC is reconfigured via ADC0CON, the voltage ADC and temperature ADC are also reset.
Description
Current channel ADC enable.
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.
IIN current source enable.
00 = disables current sources.
01 = enables 50 μA current source on IIN+.
10 = enables 50 μA current source on IIN−.
11 = enables 50 μA current source on both IIN− and IIN+.
Not used. These bits are reserved for future functionality and should be written as 0.
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.
Not used. This bit is reserved for future functionality and should be written as 0.
Current channel ADC inputs select.
00 = IIN+ and IIN− are selected.
01 = IIN− and IIN− are selected. Diagnostic, internal short configuration.
10 = VREF/136 and 0 V are selected. Diagnostic, test voltage for gain settings ≤ 128. If the reference REG_AVDD and
AGND divided by 2 is selected, REG_AVDD is used for VREF. This leads to ADC0DAT being scaled by 2.
11 = not defined.
Current channel ADC reference select.
00 = internal 1.2 V precision reference is selected. In ADC low power mode, the voltage reference selection is controlled
by ADCMDE[5].
01 = external reference inputs VREF and GND_SW are selected.
10 = external reference inputs divided by 2 (that is, VREF and GND_SW divided by 2) are selected, which allows an
external reference up to REG_AVDD.
11 = the reference REG_AVDD and AGND divided by 2 is selected.
Current channel ADC gain select. The nominal I-ADC full-scale input voltage is VREF/gain.
0000 = I-ADC gain of 1.
0001 = I-ADC gain of 2.
0010 = I-ADC gain of 4.
0011 = I-ADC gain of 8.
0100 = I-ADC gain of 16.
0101 = I-ADC gain of 32.
0110 = I-ADC gain of 64.
0111 = I-ADC gain of 128.
1000 = I-ADC gain of 256.
1001 = I-ADC gain of 512.
1010 = I-ADC gain is undefined.
1011 = I-ADC gain is undefined.
1100 = I-ADC gain is undefined.
1101 = I-ADC gain is undefined.
1110 = I-ADC gain is undefined.
1111 = I-ADC gain is undefined.
