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.
