EPWM的中断嵌套设置：

__interrupt void epwm1ISR(void)
{
    //
    // Save IER register on stack
    //
    volatile uint16_t tempPIEIER = HWREGH(PIECTRL_BASE + PIE_O_IER3);
    
    //
    // Set the global and group priority to allow CPU interrupts
    // with higher priority

    IER |= M_INT3;
    IER &= MINT3;
    HWREGH(PIECTRL_BASE + PIE_O_IER3) &= MG3_1;
    
    //
    // Clear INT flag for this timer
    //
    EPWM_clearEventTriggerInterruptFlag(EPWM1_BASE);
    
    //
    // Enable Interrupts
    //
    Interrupt_clearACKGroup(0xFFFFU);
    __asm("  NOP");
    EINT;
    
    // Insert ISR Code here.......
    epwm_ISR();
    
    //
    // Disable interrupts and restore registers saved:
    //
    DINT;
    HWREGH(PIECTRL_BASE + PIE_O_IER3) = tempPIEIER;

    //Add ISR to Trace
    traceISR[traceISRIndex % TRACE_SIZE] = 0x0017;
    traceISRIndex++;
    
}
