Preface
This book is the primary reference and programming guide for the
LSI Logic PCI to SCSI I/O Processors. It contains a complete functional
description for the LSI Logic PCI to SCSI I/O Processors and includes
complete physical and electrical specifications for the LSI Logic PCI to
SCSI I/O Processors.
Audience
This manual is written for users who are familiar with the SCSI and PCI
specifications, and have a working knowledge of computer architectures
and programming. It is specifically designed for use with programming
the LSI Logic SCSI SCRIPTS™ processor in the following chip families:
• LSI53C7XX
• LSI53C8XX
• LSI53C10XX (up to the LSI53C1010 and LSI53C1010R)
Organization
This document has the following chapters and appendixes:
• Chapter 1, Using the Programming Guide, introduces the
SCRIPTS processor features and functions, and the parts of the PCI
to SCSI system that are involved in operating the chip.
• Chapter 2, Programming with SCRIPTS, describes the SCRIPTS
processor and programming language in depth, including how
SCRIPTS programs are integrated with “C” code to execute SCSI
commands.
• Chapter 3, The SCSI SCRIPTS Processor Instruction Set,
describes the SCRIPTS processor instruction set, along with detailed
iv Preface
functional descriptions and usage guidelines for all of the instructions
supported.
• Chapter 4, Using the LSI Logic Assembler NASM™, describes
use and operation of the LSI Logic Assembler (NASM).
• Chapter 5, The NASM Output File, describes the LSI Logic
Assembler (NASM) output file.
• Chapter 6, Using the Registers to Control Chip Operations,
contains functional and address information on the
LSI53C7XX/8XX/10XX family chips register set.
• Chapter 7, Integrating SCRIPTS Programs into “C” Language
Drivers, illustrates the relationship between the SCRIPTS program
and the “C” language device driver.
• Chapter 8, Writing Device Drivers with SCRIPTS, addresses
specific kinds of driver applications, with code samples for all
applications discussed.
• Chapter 9, SCRIPTS Programming Topics, addresses specific
kinds of driver applications, with code samples for all applications
discussed.
• Chapter 10, Multithreaded I/O, contains guidelines for writing
SCRIPTS for multithreaded applications.
• Chapter 11, Using the SCRIPTS Processor in Target
Applications, provides guidelines that are specific to using the
SCRIPTS processor in a target device.
• Chapter 12, Debugging the SCRIPTS Processor, provides
information on debugging SCRIPTS programs.
