Software requirements
=====================
Phytec Flash Tools (part of RDK 591)
  www.phytec.com
Raisonance 8051 compiler system - EVAL version sufficient
  www.raisonance.com
or Keil 8051 Compiler System - EVAL version sufficient
  www.keil.com
Optional: Development Assistant-C by RistanCASE

Tested using
============

Raisonance 51 Toolset version 6.1.1

Application description
=============================================
Raisonance specific files have their names prefixed with 'r'.
Keil specific files have their names prefixed with 'k'.
The same source files are used for both compilers.

This program demonstrates the 8051 port of the Memory Test Library written by Michael Barr

The library consists of four functions:

extern datum memTestDataBus(volatile datum xdata * address);
  - tests the data bus
extern datum xdata *memTestAddressBus(volatile datum xdata * baseAddress, unsigned long nBytes);
  - tests the address bus
extern datum xdata *memTestDevice(volatile datum xdata * baseAddress, unsigned long nBytes);
  - tests the memory device
extern int memTest(void);
  - performs all three tests in order and returns a pass or fail result
