DSP5509A EHPI配置成General-Purpose I/O的问题
main()
{
//int i = 0;
CSL_init();
/*设置系统的运行速度为144MHz*/
PLL_config(&myConfig);
*( volatile unsigned int*)0x6c00=0x0003; //EBSR
*( volatile unsigned int*)0x4403=0x003F; //EHPIGPIOEN
*( volatile unsigned int*)0x4404=0x003F; //EHPIGPIODIR
*( volatile unsigned int*)0x4405=0x0000; //EHPIGPIODATA
while(1)
{
*(volatile unsigned int*)0x4405=0x003F;
delay();
*(volatile unsigned int*)0x4405=0x0;
delay();
}
}

程序如让所示，编译连接下载正常，寄存器的值也正确，但A13至A8没有相应的输出。请问是哪里出现了问题，是不是哪里设置没有考虑到。求解释
