* ADDITIONAL NOTES:
* 1. This file contains trap service routines (handlers) for hardware
*    exceptions generated by the dsPIC33F device.
* 2. All trap service routines in this file simply ensure that device
*    continuously executes code within the trap service routine. Users
*    may modify the basic framework provided here to suit to the needs
*    of their application.
