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
high state (V

Note:
HIGH-VOLTAGE INCREMENT 1
(FOR MCP402X COMPATIBILITY)
This command allows compatibility with
the MCP402X family, which supports
updating of the non-volatile wiper setting
with the WiperLock Technology feature.

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