The first logic “1” bit, after CS goes low, defines the beginning of the Control Byte
1 = unipolar, 0 = bipolar. Selects unipolar or bipolar conversion mode. In unipolar mode, analog
input signals from 0 to +12V (MAX1132) or 0 to V
mode analog input signals from -12V to +12V (MAX1132) or -V
converted.
Selects the internal or external conversion clock. 1 = Internal, 0 = External.
These three bits are stored in a port register and output to pins P2, P1, P0 for use in addressing
a mux or PGA. These three bits are updated in the port register simultaneously when a new
Control Byte is written.
