= unipolar,
0
= bipolar. Selects unipolar or bipolar conversion mode. In unipolar mode, an
analog input signal from 0V to V
REF
can be converted; in bipolar mode, the signal can range
from -V
REF
/ 2 to +V
REF
/ 2.
1
= single ended,
0
= differential. Selects single-ended or differential conversions. In single-
ended mode, input signal voltages are referred to GND. In differential mode, the voltage dif-
ference between two channels is measured. (Tables 3 and 4.)
Selects clock and power-down modes.

These three bits select which of the eight channels is used for the conversion
(Tables 3 and 4).
