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 VCC
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 VSS. 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.
RTOTAL with VCC Removed
The end to end resistance of the array will fluctuate
once VCC is removed.
