Example description
===================
This example guides the user to :
- configure GPIO4 as output push-pull
- write on the GPIO4 port

It is made of 3 steps :
1) GPIO4 configuration in output push-pull mode to use STR73x-Eval board's leds

2) Drive leds connected to the GPIO4 pins:
    - Set led connected to PIN0
    - Reset led connected to PIN0
    - Set GPIO4 LSB
    - Set GPIO4 MSB
    - Reset all GPIO4 pins
    - Set all GPIO4 pins

3) Make a loop on all GPIO4 connected leds
   - Set  GPIO4 pins one by one in a sequence. 

Directory contents
==================
73x_conf.h  Library Configuration file
73x_it.c    Interrupt handlers
main.c      Main program

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 :
  + 73x_lib.c
  + 73x_cfg.c
  + 73x_gpio.c
- Link all compiled files and load your image into either RAM or Flash
- Run the example
- Check the toggling of GPIO4 pins.
