/*
* 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.
