FAS466  SAMPLE CODE SET  
REVISION B.1
7/15/2002
======================================================================

This sample codeset is a preliminary version that will eventually be
used for the evaluation card when it is available.  This code has only
been compiled and linked with no errors and has yet to be tested with
actual hardware.  It is intended to be only used as a reference for
configuring the FAS466  to perform SCSI activities.

CODESET FILES DESCRIPTION
--------------------------------------------

HEADER FILES

fas466defs.h
==============
This header file contains miscellaneous definitions, such as SCSI 
Commands, Status Codes, and SCSI Messages.  It contains other 
definitions as well.


fas466globalvars.h
====================
This header files contains all global variables.

fas466regs.h
====================
This header file contains the register addresses of all FAS566 
registers and the external DMA controller.


fas466_size.c
===========
This source file defines the size (byte, word, wide word) of all FAS566
registers in preparation for access from the processor.

interface.c
===========
This source file faciliates access to the chip registers by defining
functions to read and ite to registers, as well as bit setting and
clearing.

				
Initiator_Mode_wr_rd.c
==================
This source file contains code to issue a SCSI WRITE(6) and READ(6) command.  It
sets up the SC,  and DMA to recieve/send data from the SCSI to the external DMA Controller.
