DSP56602 Datasheet, PDF (27/340 Pages) Motorola, Inc – 16-Bit Digital Signal Processor User manual

DSP56602 Overview
Introduction
1.1 INTRODUCTION
This manual describes the DSP56602 16-bit Digital Signal Processor (DSP), its memory
and operating modes, and its peripheral modules. This manual is intended to be used
with the DSP56600 Family Manual (DSP56600FM/AD), which describes the Central
Processing Unit (CPU), programming models, and instruction set details. The DSP56602
Technical Data Sheet (DSP56602/D) provides electrical specifications, timing, pinout, and
packaging descriptions on the DSP56602. These documents, as well as Motorola’s DSP
development tools, can be obtained through a local Motorola Semiconductor Sales Office
or authorized distributor.
To receive the latest information, access the Motorola DSP home page located at the
address listed on the back cover of this document.
The DSP56602 is a member of the DSP56600 core-based family of programmable CMOS
DSPs. This general purpose DSP combines processing power with configuration
flexibility, making it an excellent cost-effective solution for signal processing and control
functions.
This manual is arranged in the following sections:
• Section 1—DSP56602 Overview provides a brief overview of the DSP56602,
describes the structure of this document, and lists other documentation necessary
to use this chip.
• Section 2—Signal/Connection Description provides a description of the signals
present on the pins of the DSP56602, and how these signals are grouped into the
various interfaces.
• Section 3—Memory Maps describes the on-chip memory, structures, registers, and
interfaces.
• Section 4—Core Configuration describes the registers that must be programmed
to properly configure the DSP56600 core when using the DSP56602.
• Section 5—External Memory Interface (Port A) describes the External Memory
Interface, which is also referred to as Port A.
• Section 6—GPIO describes the dedicated General Purpose Input/Output (GPIO)
interface, and the alternate GPIO functionality provided on certain on-chip
interfaces.
• Section 7— Host Interface (HI08) describes the 8-bit HI08 Host Interface.
• Section 8—Synchronous Serial Interface describes the 16-bit Synchronous Serial
Interface (SSI), which communicates with devices such as codecs, other DSPs,
