Chapter 3
Digitized Sound I/O Programming
This chapter discusses the techniques of programming the DSP for digitized sound
I/O and introduces the operational methods and modes available. It assumes that you
have some working knowledge on programming the DMA controller and the
Programmable Interrupt Controller.
This chapter is divided into two sections. The first section describes the various
digitized sound operation modes. The second section provides the step by step
procedures needed to perform the various modes of digitized sound operation
described in the first part. Simple C language I/O port instructions are also included
in the second section to help you use the steps presented effectively.
