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 IER0x0000; IFR0x0000; 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.SCIRXINTAsciaRxFifoIsr;) 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led 闪烁实验

// DESCRIPTION:
//
// Three different examples are included. Select the example
// (data, set/clear or toggle) to execute before compiling using
// the #define statements found at the top of the code.
//
//
// Toggle all of the GPIO PORT pins
//
// The pins can be observed using Oscilloscope.
