The Increment/Decrement command is different from the
other commands. Once the command is issued and the
X9408 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
detailed illustration of the sequence and timing for this
operation are shown in Figures 5 and 6 respectively.
