This mode is achieved by initializing the U/D pin to a
high state (V
CS pin. Subsequent rising edges of the U/D pin incre-
ments the wiper setting toward terminal A. This is
shown in Figure 5-2.
After the wiper is incremented to the desired position,
the U/D pin should be driven low (V
should be forced to V
transitions on the U/D pin do not cause the wiper set-
ting to increment. Driving the CS pin to V
occur as soon as possible (within device specifications)
after the last desired increment occurs.

When the device voltage falls below the RAM retention
voltage of the device, the wiper state may be corrupted.
When the device returns to the operating range, the
wiper will be loaded with the Default POR wiper setting.
After the CS pin is driven to V
serial command may immediately be entered.

Note:
The wiper value will not overflow. That is,
once the wiper value equals 0x3F,
subsequent increment commands are
ignored.
