12-/16-Bit DASs with ADC, DACs, DPIOs, APIOs,
Reference, Voltage Monitors, and Temp Sensor
The ADC Setup register configures the input multiplexer,
ADC gain, and unipolar/bipolar modes to perform a data
conversion. Changes made to the ADC Setup register
settings are applied immediately. If changes are made
during a conversion in progress, discard the results of
that conversion to ensure a valid conversion result.
MSEL: Multiplexer Select bit (default = 0). The MSEL bit
selects the upper or lower multiplexer. MSEL = 0 selects
the upper mux and MSEL = 1 selects the lower mux.

MUX<3:0>: Multiplexer Input Select bits (default =
0000). The MUX<3:0> bits plus the MSEL bit select the
inputs to the ADC (see Tables 7 and 8).
GAIN<1:0>: ADC Gain bits (default = 00). The
GAIN<1:0> bits select the gain of the ADC (see Table 9).
BIP: Unipolar-/Bipolar-Mode Selection bit (default = 0).
For unipolar mode, set BIP = 0. For bipolar mode, set
BIP = 1. For temperature-sensor conversions, use the
default GAIN = 00 and BIP = 0.
