Example description
===================
This example demonstrates how to configure the XTI to generate IRQ interrupts.
This example highlights one of the features of the XTI which is to generate an
IRQ interrupt service routine and use the P0.15 pins (tied to the wakeup button 
monted on the MB393 board)to execute the interrupt code.
If the program work properly you will see the Led connected to the P0.0 
pin (LD6 on the  MB393 board) change state every time when you press the wakeup
button.

 
Directory contents
==================
 71x_conf.h  Library Configuration file
 71x_it.c    Interrupt handlers
 71x_it.h    Interrupt handlers header file
 main.c      Main program
 

Hardware environment
====================
This example works as standalone on the STR71x-Eval board (mb393) and extra 
hardware implementation is not required to run the example.


How to use it
=============
In order to make the program work, you must do the following :
- Create a project and setup all your toolchain's start-up files
- Compile the directory content files and required Library files :
  + 71x_lib.c
  + 71x_gpio.c
  + 71x_apb.c
  + 71x_rccu.c
  + 71x_eic.c
  + 71x_xti.c

- Link all compiled files and load your image into either RAM or FLASH
- Run the example  
- A square signal must be applied to the P0.15 pin (using wakeup button).
