Can be set in input or output mode in units
of 8 bits. In external memory expansion
mode, this port functions as multiplexed
address/data bus (AD0-AD7).
Can be set in input or output mode in
1-bit units. In external memory expansion
mode, this port functions as address bus
(A8-A15).
Can be set in input or output mode in
1-bit units. In external memory expansion
mode, P90 outputs RD strobe signal, and
P91 outputs WR strobe signal.
Sets port 4 in input or output mode in units
of 8 bits. In external memory expansion
mode, sets memory expansion width of ports
4 and 5.
Sets port 5 in input or output mode in
1-bit units.
In ordinary operation mode:
MODE0, 1 = LL
In ROM-less mode:
MODE0, 1 = HH

Always functions as multiplexed address/
data bus (AD0-AD7).
Always functions as address bus (A8-A15)
P90 always functions as RD strobe signal
output pin, and P91 always functions as WR
strobe signal output pin. P92 and P93
function as I/O port lines.
Always fixed to external memory expansion
mode.
None
Always set as follows:
