/* * 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. * * Authors: Ralf Corsepius (corsepiu@faw.uni-ulm.de) and * Bernd Becker (becker@faw.uni-ulm.de) * * COPYRIGHT (c) 1997-1998, FAW Ulm, Germany * * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE * * * COPYRIGHT (c) 1998. * On-Line Applications Research Corporation (OAR). * Copyright assigned to U.S. Government, 1994. * * The license and distribution terms for this file may be * found in the file LICENSE in this distribution or at * http://www.OARcorp.com/rtems/license.html. * * Modified to reflect isp entries for sh7045 processor: * John M.
