This mode is achieved by initializing the U/D pin to a
low state (V
Subsequent rising edges of the U/D pin decrement the
wiper setting toward terminal B. Set the U/D pin to the
low state (V

Note:
The wiper value will not underflow. That is,
once the wiper value equals 0x00,
subsequent decrement commands are
ignored.
