This example shows how to configure external interrupt lines.
In this example, 2 EINT lines (KEY1,KEY2) when using the G32R430 TINY BOARD
are configured to generate an interrupt on each falling edge. In the interrupt
routine a led connected to a specific GPIO pin is toggled.

In this example
    - EINT1  is mapped to PC1
    - EINT2  is mapped to PC2

After EINT configuration
  when falling edge is detected on EINT1 , LED1 toggles
  when falling edge is detected on EINT2 , LED2 toggles
