AT89S8252, AT89S53 SPI Program, This program shows how to configure and use the SPI in master mode

Serial Peripheral Interface (SPI) Example Program
=================================================
This example program shows how to configure and use the SPI in a
master mode for the following microcontrollers:

   * ATMEL AT89S53
   * ATMEL AT89S8252

To run this program...

1. Choose your target
2. Build the project (Project Menu, Build Target)
3. Start the debugger (Debug Menu, Start/Stop Debug Session)
4. View the Serial Window (View Menu, Serial Window #1)
5. View the SPI peripheral (Peripheral Menu, SPI)
6. View the Port 1 (Peripheral Menu, I/O Port)
7. Display the memory area X:0x700000.
8. Run the program (Debug Menu, Go)

A debug script (SPI_AT250X0.ini) includes debugger signal functions that
simulate an Atmel AT250X0 SPI memory device.  This device is simulated
using a simple state machine implemented with switch statements.
