  @Summary:
    This is the generated header file for the EXT_INT driver using MPLAB(c) Code Configurator

  @Description:
    This header file provides APIs for driver for EXT_INT. 
    Generation Information : 
        Product Revision  :  MPLAB(c) Code Configurator - pic24-dspic-pic32mm : v1.25
        Device            :  dsPIC33EV256GM004
        Driver Version    :  1.0
    The generated drivers are tested against the following:
        Compiler          :  XC16 1.26
