Global Data Memory
4-13
Memory and I/O Spaces
toggled between local memory and global memory. For example, in the system
of Figure 4–6, when GREG = XXXXXXXX00000000
2
(no global memory), the
local data RAM is fully accessible; when GREG = XXXXXXXX10000000
2
(all
global memory), the local data RAM is not accessible.
