Example description
===================
This example shows a nested interrupt case.
Three interrupts are configured as follow:

- TIM0 Output Compare 2 interrupt with priority "0" triggered each 100s.
- EXTIT0 software interrupt with priority "1" triggered each time we enter TIM0 
  Output Compare 2 interrupt.
- EXTIT1 software interrupt with priority "2"  triggered each time we enter 
  EXTIT0 software interrupt.

You can scope the entrance and the exit from each interrupt respectively through 
GPIO0.2, GPIO0.0, and GPIO0.1.



Directory contents

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 :
  + 91x_lib.c
  + 91x_tim.c
  + 91x_gpio.c
  + 91x_scu.c
  + 91x_rtc.c
  + 91x_vic.c
      
- Link all compiled files and load your image into either RAM or Flash
- Run the example
