Figure 3. Two-Byte Command Sequence
Figure 4. Three-Byte Command Sequence
The Increment/Decrement command is different from
the other commands. Once the command is issued
and the X9438 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
HIGH
) while SDA is HIGH, the selected wiper will
move one resistor segment towards the V
H
terminal.
Similarly, for each SCL clock pulse while SDA is LOW,
the selected wiper will move one resistor segment
towards the V
L
terminal. A detailed illustration of the
sequence for this operation is shown in Figure 5.
