0002  * This file contains the isp frames for the user interrupts.
0003  * From these procedures __ISR_Handler is called with the vector number
0004  * as argument.
0005  *
0006  * __ISR_Handler is kept in a separate file (cpu_asm.c), because a bug in
0007  * some releases of gcc doesn't properly handle #pragma interrupt, if a
0008  * file contains both isrs and normal functions.
