Increment/Decrement Command
The final command is Increment/Decrement (See Figures 6
and 7). The Increment/Decrement command is different from
the other commands. Once the command is issued and the
X9251 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 SCK clock pulse (tHIGH) while SI is HIGH, the
selected wiper moves one wiper position towards the RH
terminal. Similarly, for each SCK clock pulse while SI is
LOW, the selected wiper moves one wiper position towards
the RL terminal. A detailed illustration of the sequence and
timing for this operation are shown. See Instruction format
for more details.
