For the reserved values, all input switches are disabled to avoid leakage or other undesir-

able operation. ADC samples taken with reserved bit settings are undefined.

Single-Ended:

0000 = ANA0 (transimpedance amp output when enabled)

0010 = ANA2 (transimpedance amp non-inverting input)

0011 = ANA3

0100 = ANA4

0101 = ANA5

0110 = ANA6

0111 = ANA7

1000 = Reserved
