Potentiometer Wiper Setting
If 00 or 01 are the values of the two MSBs of the
Command Byte, then the wiper settings of the poten-
tiometers are to be programmed. The lower 6 LSBs of
the Command Byte are then used to store the wiper
settings for the selected potentiometer. See below for
the potentiometer wiper setting details.

Configuration Selection: Selects which potentiometer will be programmed.
00 = Potentiometer 0 will be programmed.
01 = Potentiometer 1 will be programmed.
bits 5–0
These bits determine the wiper setting of the selected potentiometer. Available wiper settings are determined by
the attenuation option as described in the Configuration Register section.
