Functions

(Port A)

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

set in a unit of signle bits.

Incorporation of the pull-

up resistance can be set

through the software in a

unit of 4 bits.

(8 pins)

Analog inputs to A/D converter.

(8 pins)

External capture input to 16-bit timer/counter.

(Port B)

I/O can be set in a unit

of single bits for lower

7 bits. Incorporation of

pull-up resistor can be

set through the software

in a unit of 4 bits.

(8 pins)

Chip select input for serial interface (CH0).

Serial clock I/O (CH0).

Serial data input (CH0).

Serial data output (CH0).

Serial clock I/O (CH1).

Serial data input (CH1).

Serial data output (CH1).

(Port C)

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

12mA sync current. Incorporation of pull-up resistor can be set through

the software in a unit of 4 bits.

(8 pins)

(Port D)

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

up resistor can be set through the software in a unit of 4 bits.

(8 pins)

(Port E)

6-bit port. Lower 4 bits

are for inputs; upper

2 bits are for outputs.

(6 pins)

(Port F)

Lower 7 bits are for

output; of which lower

4 bits are large current

(12mA) N-ch open

drain output.

The uppermost bit

(PF7) is for input.

(8pins)

External event inputs for timer/counter.

(2 pins)

Remote control reception circuit input.

Non-maskable interruption request input.

Rectangular wave output for 16-bit timer/counter.

Output for 32kHz oscillation frequency division.
