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

Note:
The wiper value will not overflow. That is,
once the wiper value equals 0x3F,
subsequent increment commands are
ignored.
