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.
1xxx = I-ADC gain is undefined.
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) are selected.
10 = external reference inputs divided-by-two (VREF, GND_SW)/2 are selected, this allows an external reference up to
REG_AVDD.
11 = (REG_AVDD, AGND) divided-by-two selected.
