这是什么意思啊           
  *(volatile unsigned short *)(0x0000AAAA)=0xAAAA;
*(volatile unsigned short *)(0x00005554)=0x5555;
*(volatile unsigned short *)(0x0000AAAA)=0x8080;
*(volatile unsigned short *)(0x0000AAAA)=0xAAAA;
*(volatile unsigned short *)(0x00005554)=0x5555;

C语言里的知识，
(volatile unsigned short *)(0x0000AAAA)是将0x0000AAAA数字转换成volatile unsigned short *指针，
*(volatile unsigned short *)(0x0000AAAA)是取该指针所指存储空间的内容
*(volatile unsigned short *)(0x0000AAAA)=0xAAAA;也就是向0x0000AAAA地址写入0xAAAA
