The wiper, when at either fixed terminal, acts like its
mechanical equivalent and does not move beyond the
last position. That is, the counter does not wrap
around when clocked to either extreme.
AUTOSTORE
The value of the counter is stored in EEPROM mem-
ory whenever the chip senses a power-down of V
CC
while ASE is enabled (held LOW). When power is
restored, the content of the memory is recalled and the
counter reset to the last value stored.
If AUTOSTORE is to be implemented, ASE
is typically
hard wired to V
SS
. If ASE is held HIGH during power-
up and then taken LOW, the wiper will not respond to
the PU
or PD inputs until ASE is brought HIGH and
held HIGH.
Manual (Push Button) Store
When ASE
is not enabled (held HIGH) a push button
switch may be used to pull ASE
LOW and released to
perform a manual store of the wiper position.

COMMENT
Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only; functional operation of the
device (at these or any other conditions above those
listed in the operational sections of this specification) is
not implied. Exposure to absolute maximum rating con-
ditions for extended periods may affect device reliability.

POWER-UP AND POWER-DOWN REQUIREMENTS
The are no restrictions on the sequencing of V
CC
and the voltage applied to the potentiometer pins during power-up
or power-down conditions. During power-up, the data sheet parameters for the DCP do not fully apply until 1ms after
V
CC
reaches its final value. The V
CC
ramp rate spec is always in effect.
