ADC_IP_SELECT

Select which node to multiplex to the ADC. All unlisted 5-bit codes are reserved

and returns an ADC result of zero.

01100: ADC2 pin input.

01101: voltage on +VSENSE buffer output.

01110: voltage on −VSENSE buffer output

01111: ADC1 pin input (0 V to 1.25 V input range).

10000: ADC1 pin input (0 V to 0.5 V input range).

10001: ADC1 pin input (0 V to 2.5 V input range).

10010: ADC1 pin input (±0.5 V input range).

10011: reserved (do not select this option).

10100: INT_AVCC.

10101: VLDO.

10110: VLOGIC.
