The Command Byte determines both the potentiometer
wiper settings and the configuration of both poten-
tiometers. This is done by setting the two MSBs of the
Command Byte to one of three values. If 00 is set as
the value for the two MSBs, then the wiper setting for
Potentiometer 0 is to be programmed. If 01 is set as the
value, then the wiper setting of Potentiometer 1 is to be
programmed. See the Potentiometer Wiper Setting sec-
tion for more details about writing the wiper setting. A
value of 10 indicates that the Configuration Register is
to be programmed. A value of 11 is reserved and is not
to be used. See the Configuration Register section for
more information. Any values other than the three dis-
cussed above will result in no action by the part. See
below for the Command Byte structure.
