P00 (

SCK

)

I/O (I/O)

SIO1 Serial clock input/output

P17 (INT4/TC3)

External interrupt 4 input or

Timer Counter 3 input

P16 (INT2)

External interrupt 2 input

P15 (INT3/TC1)

I/O (Input)

External interrupt 3 input or Timer

Counter 1 input

P14 ( PDO / PWM )

I/O (Output)

PWM output or programmable divider output

P13 ( DVO )

I/O (Output)

Divider output

P12 (TC2/ PPG )

I/O (I/O)

Timer counter input 2 or programmable pulse

generator output

P11 (INT1)

External interrupt input 1

P10 (

INT

)

I/O (Input)

Two 8-bit programmable input/output

ports (tri-state).

Each bit of these ports can be

individually configured as an input or

an output under software control.

During reset, all bits are configured

as inputs.

When used as a PPG output or a

divider output, the output latch must

be set to “1”.

External interrupt input 0

P22 (XTOUT)

I/O (Output)

P21 (XTIN)

Resonator connecting pins (32.8 kHz).

For inputting external clock, XTIN is used and

XTOUT is opened.

P20 (

INT

/ STOP )

I/O (Input)

3-bit input/output port with latch.

When used as an input port, a

resonator connecting pin, an

external interrupt input, or a STOP

mode release input, the output latch

must be set to “1”.

External interrupt input 5 or STOP mode release

signal input

P32 (

SCK

)

I/O (Input)

SIO0 clock input/output

P31 (SDA/SO0)

I/O (I/O/Output)

2C bus data input/output or SIO0 data output

P30 (SCL/SI0)

I/O (I/O/Input)

3-bit programmable input/output port

(tri-state/programmable open drain).

Each bit of the port can be individully

configured as an input or an output

under software control.

When used as a serial interface

output, the output latch must be set

to “1”.

2C bus clock input/output or SIO0 data input

P47 (AIN7)

to P40 (AIN0)

I/O (Input)

P53 (AIN13)

to P50 (AIN8)

I/O (Input)

8/4-bit programmable input/output

port (tri-state).

Each bit of the port can be

individually configured as an input or

output under software control.

When used as an analog input set to

input mode.

AD converter analog inputs

P67 (V7) to P60 (V0)

P77 (V15) to P70 (V8)

P87 (V23) to P80 (V16)

P97 (V31) to P90 (V24)

8-bit high breakdown voltage output

ports with the latch.

When used as an vacuum

fluorescent tube driver output, the

output latch must be cleared to “0”.

PD4(V36) to PD0 (V32)

I/O (Output)

5-bit high breakdown voltage output

ports with the latch.

When used as an vacuum

fluorescent tube driver output, the

latch must be cleared to “0”.

VTF output
