Figure 6. Three-Byte Command Sequence (Read)
Figure 7. Increment/Decrement Command Sequence
Increment/Decrement
The final command is Increment/Decrement. It is differ-
ent from the other commands, because it’s length is
indeterminate. Once the command is issued, the mas-
ter can clock the selected wiper up and/or down in one
resistor segment steps; thereby, providing a fine tuning
capability to the host. For each SCK clock pulse (tHIGH)
while SI is HIGH, the selected wiper will move one
resistor segment towards the VH terminal. Similarly, for
each SCK clock pulse while SI is LOW, the selected
wiper will move one resistor segment towards the VL
terminal. A detailed illustration of the sequence and tim-
ing for this operation are shown in Figure 7 and 8.
Write in Process
The contents of the data registers are saved to nonvol-
atile memory when the CS pin goes from LOW to
HIGH after a complete write sequence is received by
the device. The progress of this internal write opera-
tion can be monitored by a write in process bit (WIP).
The WIP bit is read with a read status command.
