PIN Name

Input/Output

Function

P07 to P00

I/O

Two 8-bit programmable input/output ports

(tri-state).

P17,P16

I/O

Each bit of these ports can be individually

P15(TC2)

I/O(Input)

Timer/Counter 2 input

configured as an input or an output under

I/O(Output)

Programmsble pulse generator output

P14(PPG)

software control.

P13(OVO)

Divider output

During reset,all bits are configured as in-

P12(INT2/TC1)

I/O(Input)

External interrupt input 2 or Timer/Counter 1 input

puts.

P11(INT1)

When used as a divider output or a PPG

External interrupt input 1

output, the latch must be set to “1”.

External interrupt input 0

P10(INT0)

P22(XTOUT)

I/O(Output)

3-bit input/output port with latch.

Resonator connecting pins(32.8kHz). For inputting

external clock,XTIN is used and XTOUT is opeded.

P21(XTIN)

I/O(Input)

When used as an input port,the latch must

be set to “1”.

External interrupt input 5 or STOP mode retease signal input

P20(INT5/STOP)

P51,P50

Output

2-bit output port with latch.

P67 to P60

I/O(Output)

8-bit programmable input/output port (tri-

state). Each bit of the port can be indi-

vidually configured as an input or an out-

put under software control.

P77(HSO)

I/O(Output)

8-bit programmable input/output port (tri-

HSO serial data output

state).

P76(HSCK)

HSO serial clock output

P75(SO)

SIO serial data output

P74(SI)

When used as an input port, a SIO input/

SIO serial data input

I/O(I/O)

SIO serial clock input/output

P73(SCK)

output on external interrupt input or a

P72(PWM/PDO)

I/O(Output)

8-bit PWM output or 8-bit programmable divider output

PWM/PDO output, the latch must be set

P71(INT4)

I/O(Input)

External interrupt input 4

to “1”.

P70(INT3/TC3)

External interrupt input 3 or Timer/Counter 3 input

XIN/XOUT

Input,Output

Resonator connecting pins for high-frequency clock.

For inputting external clock. XIN is used and XOUT is opend.

I/O

Reset signal input or watchdog timer output/address-trap-reset output/system-

RESET

clock-reset output.

TEST

Input

Test pin for out-going test. Be tied to low.

VDD,VSS

Power Supply

+5V,0V(GND)

N.C.

Be tied to low.
