+ * 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.
