(Port A)

8-bit I/O port.

I/O can be set in a

unit of single bits.

(8 pins)

(Port B)

8-bit I/O port. I/O can be set in a unit of single bits.

(8 pins)

(Port C)

Lower 6 bits are I/O ports; I/O can be set in a unit of single bits. Upper 2bits

are output port and large current (12mA) N-channel open drain output.

Upper 2 bits are medium voltage drive (12V), lower 6 bits are 5V drive.

(8 pins)

(Port D)

8-bit I/O port.

I/O can be set in a

unit of single bits.

Can drive 12mA

sink current.

(8 pins)

(Port E)

Bits 0 and 1 are I/O

port; I/O can be set

in a unit of single.

Bits 2 and 3 are

input port.

Bits 4, 5 and 6

are output port.
