Appendix C Programmer’s Reference

C.1 Introduction

This section has been compiled as a reference for programmers. It contains a table showing the addresses

of all the DSPs memory-mapped peripherals, an interrupt address table, an interrupt exception priority

table, a quick reference to the host interface, and programming sheets for the major programmable

registers on the DSP.

C.1.1 Peripheral Addresses

Table C-1 lists the memory addresses of all on-chip peripherals.

C.1.2 Interrupt Addresses

Table C-2 lists the interrupt starting addresses and sources.

C.1.3 Interrupt Priorities

Table C-3 lists the priorities of specific interrupts within interrupt priority levels.
