4 INTERFACING
4.1
Introduction
Since the AY-3-8910/8912 PSG must be used with support compo-
nents, interfacing to the circuit is an obvious requirement. The PSG is
designed to be controlled by a microprocessor or microcomputer,
and drive directly into analog audio circuitry. It provides the link
between the computer and a speaker to provide sounds or sound
effects derived from digital inputs.
The following paragraphs provide examples and illustrations show-
ing the ease with which an AY-3-8910/8912 Programmable Sound
Generator may be utilized in a microprocessor/microcomputer
system.
