对DSP进行开发时，需要对其底层的硬件及外设进行相应的配置，当配置完成后才可以将其相应模块激活，才可以在其内部进行程序编写及调试处理。下面对程序配置及操作进行简单的整理，仅供参考。
第一步：初始化系统控制，PLL，看门狗，使能外设时钟等，一般调用函数InitSysCtrl()；
第二步：初始化GPIO，对于不同的硬件系统，进行不同的功能配置；
第三步：清除所有的中断并初始化PIE中断向量表
禁用CPU中断
DINT;
初始化PIE控制寄存器为默认状态
InitPieVectTable();
禁用CPU中断并清除所有的CPU中断标志
IER=0x0000;
IFR=0x0000;
初始化PIE中断向量表
InitPieVectTable()；
EALLOW;
XXX-------此处填写程序中需要的中断，将其映射到中断向量表中(如
Pie VectTable.SCIRXINTA=&sciaRxFifoIsr;)
EDIS;
第四步：初始化所有外设(如果没有外设结构，此部分可省略)；
第五步：用户程序段，使能中断。以上为初步设计DSP程序的基本框架，具体要实现的功能还需在其中添加！

CCS You are required to terminate existing debug…
debug后，直接点 terminate 小方框不行，ccs没停止上一次的 debug。
