Instruction Format
Notes:
(1) “A1 ~ A0”: stands for the device addresses sent by the master.
(2) WPx refers to wiper position data in the Counter Register
(3) “I”: stands for the increment operation, SI held HIGH during active SCK phase (high).
(4) “D”: stands for the decrement operation, SI held LOW during active SCK phase (high).
