PIN DESCRIPTIONS
V
The high (V
equivalent to the fixed terminals of a mechanical potenti-
ometer. The minimum voltage is –5V and the maximum is
+5V. It should be noted that the terminology of V
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:
V
down an automatic store cycle takes place.
V
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
position to the E
