Internal RAM
External Data Memory Map –
The address decode block in the
LSI53C040 decodes addresses that are generated by the
microcontroller. Additionally, it multiplexes memory space accesses
between the different register and memory blocks according to the
memory map. See
Figure 2.2
for an example of this memory map.
