Pin Name

I/O

Description

Power supply

VCC

Input

Power supply pin. Connect it to the system power supply.

VCL

Input

Connect this pin to VSS via a 0.1-

F capacitor. The capacitor

should be placed close to the pin.

VSS

Input

Ground pin. Connect it to the system power supply (0 V).

PLLVCC

Input

Power supply pin for the PLL circuit. Connect it to the system

power supply.

PLLVSS

Input

Ground pin for the PLL circuit.

Clock

XTAL

Output

Pins for a crystal resonator. An external clock signal can be

input through the EXTAL pin.

EXTAL

Input

Operating mode control

MD0

MD1

MDE

Input

Pins for setting the operating mode. The signal levels on these

pins must not be changed during operation.

System control

RES#

Input

Reset signal input pin. This LSI enters the reset state when this

signal goes low.

EMLE

Input

Input pin for the on-chip emulator enable signal. When the on-

chip emulator is used, this pin should be driven high. When not

used, it should be driven low.

On-chip emulator

TRST#

Input

On-chip emulator pins. When the EMLE pin is driven high,

these pins are dedicated for the on-chip emulator.

TMS

Input

TDI

Input

TCK

Input

TDO

Output

TRCLK

Output

This pin outputs the clock for synchronization with the trace

data. Not included in the 80-/64-pin versions.

TRSYNC

Output

This pin indicates that output from the TRDATA0 to TRDATA3

pins is valid. Not included in the 80-/64-pin versions.

TRDATA0 to TRDATA3

Output

These pins output the trace information. Not included in the 80-

/64-pin versions.

Interrupt (ICU)

NMI

Input

Non-maskable interrupt request signal.

IRQ0-A/IRQ0-B/IRQ0-C

IRQ1-A/IRQ1-B/IRQ1-C

IRQ2-A/IRQ2-B

IRQ3 to IRQ7

Input

Interrupt request signals. The IRQ0-C/IRQ1-C/IRQ2-B pin is not

included in the 100-pin version. The IRQ0-B/IRQ0-C/IRQ1-C/

IRQ2-B pin is not included in the 80-pin version. The IRQ0-B/

IRQ0-C/IRQ1-B/IRQ1-/IRQ2-A/IRQ2-B/IRQ4/IRQ6/IRQ7 pin is not

included in the 64-pin version.
