DSP2802x_SWPrioritizedDefaultIsr.c和DSP2802x_DefaultIsr.c的区别和应用场合???



28027源文件里有两个中断原函数DSP2802x_SWPrioritizedDefaultIsr.c和DSP2802x_DefaultIsr.c,他们不能同时使用,那DSP2802x_SWPrioritizedDefaultIsr.c有什么特殊之处吗??

// Connected to INT13 of CPU (use MINT13 mask):
#if (INT13PL != 0)
interrupt void INT13_ISR(void) // INT13 or CPU-Timer1
{
IER |= MINT13; // Set "global" priority 开中断不是在中断外面吗,怎么在这里置位呢?这个中断触发源是什么啊
EINT;

// Insert ISR Code here

// Next two lines for debug only to halt the processor here
// Remove after inserting ISR Code
asm (" ESTOP0");
for(;;);
}
#endif

同样DSP2802x_SWPiroritizedPieVect.c和DSP2802x_PieVect.c区别???
