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 (tHIGH) while SDA is HIGH, the
selected wiper will move one resistor segment towards the
VH terminal.
Similarly, for each SCL clock pulse while SDA is LOW, the
selected wiper will move one resistor segment towards the
VL/RL terminal. A detailed illustration of the sequence and
respectively.
