1)EMIF16每个CE空间可以连接多大容量的SRAM/NOR FLASH?是按照地址线去计算的吗,32MB?NAND FLASH是支持一个CE空间64MB还是256MB?
2)通过EMIF16的NOR FLASH进行BOOT时,支持的是8bit还是16bit总线,手册中并没有明确说明。
3)DDR3的参考时钟外接50MHz时,可以工作于DDR3-800、DDR3-1066、DDR3-1333和DDR3-1600吗?如果不行,那么多少MHz的时钟可以支持这四种速率?
noaming:
A total of 256M bytes of any of these memories can be accessed at any given time via four chip
selects with 64M byte access per chip select.
关于EMIF16的信息请参看文档:KeyStone Architecture External Memory Interface (EMIF16) User Guide

The DDR3 interface can operate at 800 Mega Transfers per Second (MTS), 1033 MTS, 1333 MTS, and 1600 MTS.
