Must be logic 0 for these commands.
These commands are invalid if this bit is logic 1.
Ignore this function.
Access the respective registers, offset, gain, or channel-setup, as an array of regis-
ters. The particular registers accessed are determined by the RS bits. The registers
are accessed MSB first with physical channel 0 accessed first followed by physical
channel 1 next and so forth.
CS1-CS0 provide the address of one of the two (four for CS5533/34) physical input
channels. These bits are also used to access the calibration registers associated
with the respective physical input channel. Note that these bits are ignored when
reading data register.
Write to selected register.
Read from selected register.

These commands are invalid if this bit is logic 0.
Must be logic 1 for these commands.
Perform fully settled single conversions.
Perform conversions continuously.
These bits are used as pointers to the Channel-Setup registers. Either a single con-
version or continuous conversions are performed on the channel setup register
pointed to by these bits.
