DARAM4-7 are located in the address range 18000h-1FFFFh in program space. The DARAM located in the address range 18000h-1FFFFh in program space can be mapped into
data space by setting the DROM bit to one.
***********************************************************************
DARAM4-7物理地址在程序空间18000-1FFFF,
如果DROM=0,则DARAM4-7只能用在程序空间
如果DROM=1,则DARAM4-7可以用在程序空间,也可以用在数据空间,具体由.CMD文件分配。
///////////////////////////////////////////////////////////////////////////////////////////////////////////////
这是我的理解,你可以通过更改.CMD文件试试
