9.3.3
The external address space has a capacity of 384 Mbytes and is used by dividing eight partial
spaces (address map 1) or six partial spaces (address map 2). The kind of memory to be connected
and the data bus width are specified in each partial space. The address map for the external address
space is listed below.
