- * This is a very simple standalone application demonstrating
- * catching IRQs on the MPC52xx architecture.
- *
- * The interrupt to be intercepted can be specified as an argument
- * to the application. Specifying nothing will intercept IRQ1 on the
- * MPC5200 platform. On the CR825 carrier board from MicroSys this
- * maps to the ABORT switch :)
