Manual structure

The manual is divided into the following chapters:

This introduction chapter, which explains the structure of the book;

A notation chapter (Chapter 2) which explains the layout and notation conven-

tions used in the instruction definitions and elsewhere;

An architecture chapter (Chapter 3), which explains the structure of the ST20-

C1 core, the registers, memory addressing, the format of the instructions and

the exception handling and process models;

Four chapters on using the instructions and how the instructions can be used

to achieve certain useful outcomes: Chapter 4 on the general instructions;

Chapter 5 on multiply-accumulate; Chapter 6 on interrupts and traps; and

Chapter 7 on processes and support for multi-tasking.

An alphabetical listing of the instructions, one to a page (Chapter 8). Descrip-

tions and formal definitions are presented in a standard format with the instruc-

tion mnemonic and full name of the instruction at the top of the page. The

notation used is explained in detail in Chapter 2.

In addition there are appendices listing constants and structures, covering issues

related to compiling for a ST20-C1 core and listing the instruction set plus a glossary

for ST20-C1 terminology.
