XA-H3 MEMORY MAPS
1999 Sep 24
CMOS 16-bit highly integrated microcontroller
Code Space + Data Space = 6 MB Maximum Total with 1 MB per Chip Select. Each CS
(and thus, 1 MB space) can support either Code or Data in Harvard architecture.
*In either memory architecture, the XA-H3 can support a maximum of
6 MB because each of six Chip Selects is capable of 1 MB each. In
Unified architecture, Code and Data can share the same physical
Memory Chip and address space.
