Pin Definitions and Functions for 64-pin Package (1/3)

Function

Symbol

I/O

Description

Power supply

VCC1, VSS

Applicable as follows: VCC1 = 3.0 to 5.5 V, VSS = 0 V

Connecting pins

for decoupling

capacitor

VDC0, VDC1

—

A decoupling capacitor for internal voltage should be

connected between VDC0 and VDC1

Analog power

supply

AVCC, AVSS

Power supply for the A/D converter. AVCC and AVSS should

be connected to VCC and VSS, respectively

Reset input

RESET

The MCU is reset when this pin is driven low

CNVSS

This pin should be connected to VSS via a resistor

Debug port

NSD

I/O

This pin is to communicate with a debugger. It should be

connected to VCC1 via a resistor of 1 to 4.7 k



Main clock input

XIN

Input/output for the main clock oscillator. A crystal, or a

ceramic resonator should be connected between pins XIN

and XOUT. An external clock should be input at the XIN while

leaving the XOUT open

Main clock output XOUT

Sub clock input

XCIN

Input/output for the sub clock oscillator. A crystal oscillator

should be connected between pins XCIN and XCOUT. An

external clock should be input at the XCIN while leaving the

XCOUT open

Sub clock output XCOUT

External interrupt

input

INT0 to INT5

Input for external interrupts

NMI input

P8_5/

NMI

Input for NMI

Key input interrupt

KI0 to KI3

Input for the key input interrupt

I/O port

P0_0 to P0_3,

P1_5 to P1_7,

P2_0 to P2_7,

P3_0 to P3_3,

P6_0 to P6_7,

P7_0 to P7_7,

P8_0 to P8_4,

P8_6, P8_7,

P9_3,

P10_0 to P10_7

I/O

I/O ports in CMOS. Each port can be programmed to input or

output under the control of the direction register.

Pull-up resistors are selected for the following 4-pin units:

Pi_0 to Pi_3 and Pi_4 to Pi_7 (i = 0 to 3, 6 to 10); however,

they are enabled only for the input pins.

P7_0 and P7_1 outputs are N-channel open drain

Timer A

TA0OUT to

TA4OUT

I/O

Timers A0 to A4 input/output.

TA0OUT output assigned for port P7_0 is N-channel open

drain

TA0IN to TA4IN

Timers A0 to A4 input

Timer B

TB0IN to

TB3IN, TB5IN

Timers B0 to B3, and B5 input

Three-phase

motor control

timer output

U, V, V, W, W

Three-phase motor control timer output
