问题一:EMIF16 user guide 上有这么一段话“The EMIF16 module is intended to provide a glue-less interface to a variety of asynchronous memory devices like ASRAM, NOR and NAND memory. 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.”请问C6678的EMIF接口只有24位的地址线,16位的数据线,如果访问NorFlash,这么算下来一个片选能访问的的存储空间应该是(2^24)*2Bytes=32MBytes,为什么user guide里说的是64MBytes?
问题二:C6678的EMIF16加载模式在文档中介绍的特别简略,根本搞不清楚EMIF16的加载过程,希望技术支持能在次对EMIF16加载做一下详细描述
