The auxiliary ADC control MMR is a 16-bit register.
Description
Auxiliary channel ADC enable.
Diagnostic current source enable bits. This is the same current source as that used on ADC0DIAG[1:0]. The
ADCs cannot enable the diagnostic current sources at the same time.
[00]= current sources off.
[01] = enables a 50 μA current source on selected positive input (for example, ADC2).
[10] = enables a 50 μ A current source on selected negative input (for example, ADC3).
[11] = enables a 50 μ A current source on both selected inputs (for example, ADC2 and ADC3).
This bit must be set high if the external reference for ADC1 exceeds 1.35 V. This results in the reference
source being divided by 2.
Clear this bit when using the internal reference or an external reference of less than 1.35 V.
Auxiliary channel ADC output coding.
This bit is set to 1 by user code to configure auxiliary ADC output coding as unipolar.
This bit is cleared to 0 by user code to configure auxiliary ADC output coding as twos complement.
Auxiliary channel ADC input select. Note: Single-ended channels are selected with respect to ADC5. Bias
ADC5 to a minimum level of 0.1 V.
[0000] = ADC2/ADC3 (differential mode).
[0001] = ADC4/ADC5 (differential mode).
[0010] = ADC6/ADC7 (differential mode).
[0011] = ADC8/ADC9 (differential mode).
[0100] = ADC2/ADC5 (single-ended mode).
[0101] = ADC3/ADC5 (single-ended mode).
[0110] = ADC4/ADC5 (single-ended mode).
[0111] = ADC6/ADC5 (single-ended mode).
[1000] = ADC7/ADC5 (single-ended mode).
[1001] = ADC8/ADC5 (single-ended mode).
[1010] = ADC9/ADC5 (single-ended mode).
[1011] = internal temperature sensor+/internal temperature sensor−.
[1100] = VREF+, VREF−. Note: This is the reference selected by the ADC1REF bits.
[1101] = DAC_OUT/AGND.
[1110] = undefined.
[1111] = internal short to ADC3.
This bit is set to 1 by user code to enable the auxiliary ADC.
Clearing this bit to 0 powers down the auxiliary ADC.
