The address bus width for external output in the 1M bytes of address space can be set to 16 bits (64K bytes
address space) or 20 bits (1M bytes address space). When bit 6 of the processor mode register 0 is set to "1",
the external address bus width is set to 16 bits, and P2 and P3 become part of the address bus. P4
be used as programmable I/O ports. When bit 6 of processor mode register 0 is set to "0", the external address
bus width is set to 20 bits, and P2, P3, and P4
The external data bus width can be set to 8 or 16 bits. When the BYTE pin is "L", the bus width is set to 16 bits;
when "H", it is set to 8 bits. (The internal bus width is permanently set to 16 bits.) While operating, fix the BYTE
pin either to "H" or to "L". When the BYTE pin is "H", the data bus is set to 8 bits and P0 functions as the data bus
and P1 as a programmable I/O port. When the BYTE pin is "L", the data bus is set to 16 bits and P0 and P1 are
both used for the data bus. A software wait can also be added.
