The Increment/Decrement command is different from the
other commands. Once the command is issued and the
X9258 has responded with an acknowledge, the master can
clock the selected wiper up and/or down in one segment
steps; thereby, providing a fine tuning capability to the host.
For each SCL clock pulse (t
selected wiper will move one resistor segment towards the
V
