Static Memory Read Delay registers (EMCStaticWaitRd0-3 - 0xFFE0 820C, 22C, 24C, 26C)
和Static Memory Output Enable Delay registers (EMCStaticWaitOen0-3 - 0xFFE0 8208, 228, 248, 268)
在使用时有什么区别??
另外: Static Memory Write Delay registers0-3 (EMCStaticWaitWr - address 0xFFE0 8214, 0xFFE0 8234, 0xFFE0 8254, 0xFFE0 8274) bit description 数据手册上说是 SRAM wait state time for write accesses after the first read: 可我还是不大明白具体用在那里?
