AUTOSTORE R with V Removed TOTAL CC The value of the counter is stored in EEPROM memory The end to end resistance of the array will fluctuate once whenever the chip senses a power-down of VCC while V is removed. CC 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 . If ASE is held HIGH during power-up SS and then taken LOW, the wiper will not respond to the PU or PD inputs until ASE is brought HIGH and held HIGH.
