Application description
=============================================
This program demonstrates the XA port of the Memory Test Library written by Michael Barr

The library consists of four functions:

extern datum memTestDataBus(volatile datum far * address);
  - tests the data bus
extern datum far *memTestAddressBus(volatile datum far * baseAddress, unsigned long nBytes);
  - tests the address bus
extern datum far *memTestDevice(volatile datum far * 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

Define the constant _16BITDATABUS in the library source file and header file to test using a 16-bit data bus
Undefine the constant _16BITDATABUS in the library source file and header file to test using an 8-bit data bus
