Internal ROM

Input 14 (of which 8 are multiplexed with analog input)

I/O lines

I/O

Port 4 (P40-P47)

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).

Always 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).

Always functions as address bus (A8-A15)

Port 5 (P50-P57)

Port 9 (P90-P93)

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.

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.

Memory expansion

mode register (MM)

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.

Always fixed to external memory expansion

mode.

Port 5 mode

Sets port 5 in input or output mode in

1-bit units.

None

Setting of

• In ordinary operation mode:

MODE0, 1 = LL

• Always set as follows:

MODE0, 1 = HH

MODE0, MODE1

• In ROM-less mode:

MODE0, 1 = HH
