Example description
===================
This example provides a description of how to configure an external interrupt 
line. In this example, the EXTIT line 7 is configured to generate an interrupt 
on each falling edge. In the interrupt routine a led connected to P1.01 will be
toggled.
This led will be toggled due to the softawre interrupt generated on EXTIT Line7 
then at each falling edge.

Directory contents
==================
75x_conf.h  Library Configuration file
75x_it.c    Interrupt handlers
main.c      Main program

Hardware environment
====================
Connect a push-button to P1.05 pin with a resistor and a capacity to generate
edges on EXTIT line 7 (Key push-button in STR75x-EVAL board).
Connect a LED to P1.01 pin (LD2 in STR75x-EVAL board)

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 :
  + 75x_lib.c
  + 75x_mrcc.c
  + 75x_eic.c
  + 75x_extit.c
  + 75x_gpio.c
  
- Link all compiled files and load your image into either RAM or Flash
- Run the example
