// Step 1. Initialize System Control:
// PLL, WatchDog, enable Peripheral Clocks
// This example function is found in the DSP2833x_SysCtrl.c file.
　 InitSysCtrl();

// Step 2. Initalize GPIO:
// This example function is found in the DSP2833x_Gpio.c file and
// illustrates how to set the GPIO to it's default state.
// InitGpio();　// Skipped for this example
　 InitXintf16Gpio();　　//zq

// Step 3. Clear all interrupts and initialize PIE vector table:
// Disable CPU interrupts
　 DINT;

// Initialize the PIE control registers to their default state.
// The default state is all PIE interrupts disabled and flags
// are cleared.
// This function is found in the DSP2833x_PieCtrl.c file.
　 InitPieCtrl();

// Disable CPU interrupts and clear all CPU interrupt flags:
　 IER = 0x0000;
　 IFR = 0x0000;
