*** This readme.txt file comes with the Interrupt Handling aplication note (AN1781).

Example description
===================
 The purpose of this application note is to demonstrate how to configure the EIC
 to be able to handle nested IRQ interrupts
 The technique described in this note are of a general nature and may be applied to
 a variety of applications.

 This application note contain three examples:
 1) IRQ interrupt handling using the LDR PC method:
    - irq_ldrpc.prj located at LDR PC\realview directory.
    - Specific 71x_vect_ldrpc.s and 71x_init_ldrpc.s located at LDR PC directory
    - Specific scatter file (scat_ldrpc.scf)


 2) IRQ interrupt handling using the Branch method:
    - irq_ldrpc.prj located at Branch\realview directory.
    - Specific 71x_vect_Branch.s and 71x_init_Branch.s located at Branch directory
    - Specific scatter file (scat_Branch.scf)

 3) IRQ interrupt handling using the address method:
    - irq_Address.prj located at Address\realview directory.
    - Specific 71x_vect_Address.s and 71x_init_Address.s located at Address directory
    - Specific scatter file (scat_Address.scf)

 The main directory contain the commun files :
    - main.c   : main program
    - 71x_it.c : interrupt handler for the Timer 0 and Timer 1 (71x_vect.c)
    
This projects created using RVDK V2.1 for ST

How to use it
=============
In order to make the program work, you must do the following :
- Configure the STR710 microcontroller to boot from RAM
- Open the related .prj
- Then just compile and run it.
