5.2.4
This mode is achieved by initializing the U/D pin to a
low state (V
CS pin. Subsequent rising edges of the U/D pin
decrement the wiper setting toward terminal B. This is
shown in
After the wiper is decremented to the desired position,
the U/D pin should remain high (V
should be forced to V
transitions on the U/D pin do not cause the wiper
setting 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

Note:
The wiper value will not underflow. That is,
once the wiper value equals 0x00,
subsequent decrement commands are
ignored.
