DSP经典例子

interrupt void cpu_timer0_isr(void) {    CpuTimer0.InterruptCount++;    GpioDataRegs.GPATOGGLE.bit.GPIO4 = 1; // Toggle GPIO0 once per 500 milliseconds    GpioDataRegs.GPATOGGLE.bit.GPIO5 = 1; // Toggle GPIO1 once per 500 milliseconds    GpioDataRegs.GPATOGGLE.bit.GPIO6 = 1; // Toggle GPIO2 once per 500 milliseconds    GpioDataRegs.GPATOGGLE.bit.GPIO7 = 1; // Toggle GPIO3 once per 500 milliseconds    // Acknowledge this interrupt to receive more interrupts from group 1    PieCtrlRegs.PIEACK.all = PIEACK_GROUP1; }
