/*
 * This file contains the isp frames for the user interrupts.
 * From these procedures __ISR_Handler is called with the vector number
 * as argument.
 *
 * __ISR_Handler is kept in a separate file (cpu_asm.c), because a bug in 
 * some releases of gcc doesn't properly handle #pragma interrupt, if a 
 * file contains both isrs and normal functions.
