Before doing ;// this, the current value of ST1 is stored on the stack ;// so that the values can be restored later. The value ;// of ST1 before the masks are set is returned to the ;// user in AL. This is then used to restore their state ;// via the DSP28x_RestoreInt(Uint16 ST1) function. ;// ;// Example ;// ;// Uint16 StatusReg1 ;// StatusReg1 = DSP28x_DisableInt(); ;// ;// ... May also want to disable INTM here ;// ;// ... code here ;// ;// DSP28x_RestoreInt(StatusReg1); ;// ;// ... Restore INTM enable ;// ;//########################################################################### ;// $TI Release: 2833x/2823x Header Files V1.32 $ ;// $Release Date: June 28, 2010 $ ;// $Copyright: ;// Copyright (C) 2009-2024 Texas Instruments Incorporated - http://www.ti.com/ ;// ;// Redistribution and use in source and binary forms, with or without ;// modification, are permitted provided that the following conditions ;// are met: ;// ;// Redistributions of source code must retain the above copyright ;// notice, this list of conditions and the following disclaimer. ;// ;// Redistributions in binary form must reproduce the above copyright ;// notice, this list of conditions and the following disclaimer in the ;// documentation and/or other materials provided with the ;// distribution. ;// ;// Neither the name of Texas Instruments Incorporated nor the names of ;// its contributors may be used to endorse or promote products derived ;// from this software without specific prior written permission. ;// ;// THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS ;// "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT ;// LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR ;// A PARTICULAR PURPOSE ARE DISCLAIMED.
