应用背景最近用CYCLONE FPGA做的视频图像叠加板需要存储一些用户配置信息，而EPCS4配置芯片除了存储FPGA配置信息和NIOS II程序外，还有很多存储空间剩余未使用，刚好可以用来做用户配置信息存储。关键技术 调试过程中可以在执行alt_epcs_flash_write前手动修改epcsbuf数组内的值，在执行alt_epcs_flash_read前再更改epcsbuf数组内的值为其他值，如果执行alt_epcs_flash_read后epcsbuf数组内的值恢复到执行alt_epcs_flash_write前的值，那么对EPCS芯片的读写操作已经成功了

用AT88SC1604和IC卡读卡器（C51编写）测试表明程序可靠
