Pin Description

– 4 –

(Port A)

8-bit I/O port. I/O can be

set in a unit of single bit .

(8 pins)

(Port B)

8-bit I/O port. I/O for lower

7 bits can be set in a unit

of single bit. Uppermost

bit (PB7) is for output only.

(8 pins)

(Port C)

8-bit I/O port. I/O can be

set in a unit of single bits.

Capable of driving 12mA

synk current. (8 pins)

(Port D)

8-bit output port.

(8 pins)

(Port E)

8-bit port. Lower 6 bits are

for inputs; upper 2 bits are

for outputs.

(8 pins)

(Port F)

8-bit output port.

(8 pins)

(Port G)

8-bit I/O port. I/O can be

set in a unit of single bit.

Data for the lower 4 bits

are gated with the contents

of RTO or OR-gate output.

(8 pins)
