H16

I/O

Two 8-bit bidirectional I/O

ports P0L and P0H, bit-wise

programmable for input or

output via direction bit.

Programming an I/O pin as

input forces the

corresponding output driver

to high impedance state.

The input threshold of Port 0

is selectable (TTL or

CMOS).

In case of an external bus

configuration, Port 0 serves

as the address (A) and as

the address/data (AD) bus

in multiplexed bus modes

and as the data (D) bus in

demultiplexed bus modes.

Demultiplexed bus modes

P0L.0-P0L.7: D0-D7 (8-bit),

D0-D7 (16-bit).

P0H.0-P0H.7: I/O (8-bit),

D8-D15 (16-bit).

Multiplexed bus modes

P0L.0-P0L.7: AD0-AD7 (8-

bit), AD0-AD7 (16-bit).

P0H.0-P0H.7: A8-A15 (8-

bit), AD8-AD15 (16-bit).
