equivalent to the fixed terminals of a mechanical potenti-

ometer. The minimum voltage is –5V and the maximum is

references the relative position of the terminal in relation

to wiper movement direction selected by the

PU and PD

inputs and not the voltage potential on the terminal.

PU

The debounced

PU input is for incrementing the wiper

position. An on-chip pull-up holds the

PU input HIGH. A

switch closure to ground or a LOW logic level will, after

a debounce time, move the wiper to the next adjacent

higher tap position.

PD

The debounced

PD input is for decrementing the wiper

position. An on-chip pull-up holds the

PD input HIGH. A

switch closure to ground or a LOW logic level will, after

a debounce time, move the wiper to the next adjacent

lower tap position.

ASE

The debounced

ASE (AUTOSTORE enable) pin can be

in one of two states:

down an automatic store cycle takes place.

initiate a manual store operation. This is for a user who

wishes to connect a push button switch to this pin. For

every valid push, the X9514 will store the current wiper
