1 = unipolar, 0 = bipolar. Selects unipolar or bipolar conversion mode. In unipolar mode, an
analog input signal from 0V to VREF can be converted; in bipolar mode, the signal can range
from -VREF / 2 to +VREF / 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.

Mode
00
Full power-down (IDD = 2A, internal reference)
01
Fast power-down (IDD = 30A, internal reference)
10
Internal clock mode
11
External clock mode
These three bits select which of the eight channels is used for the conversion
(Tables 3 and 4).
The first logic 1 bit after CS goes low defines the beginning of the control byte.
