tion 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:
