/*
2 
 * This file contains the isp frames for the user interrupts.
3 
 * From these procedures __ISR_Handler is called with the vector number
4 
 * as argument.
5 
 *
6 
 * __ISR_Handler is kept in a separate file (cpu_asm.c), because a bug in
7 
 * some releases of gcc doesn't properly handle #pragma interrupt, if a
8 
 * file contains both isrs and normal functions.
