The Increment/Decrement command is different from
the other commands. Once the command is issued and
the X9409 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
/R
H
terminal. Similarly,
for each SCL clock pulse while SDA is LOW, the
selected wiper will move one resistor segment towards
the V
L
/R
L
terminal. A detailed illustration of the
sequence and timing for this operation are shown in
Figures 5 and 6 respectively.
