Pin Name

I/O

Description

Digital power supply

VCC

Input

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

Connect the pin to VSS via a 0.1-µF multilayer ceramic

capacitor. The capacitor should be placed close to the pin.

VCL

Input

Connect this pin to VSS via a 0.47-µF smoothing capacitor used

to stabilize the internal power supply. The capacitor should be

placed close to the pin.

VSS

Input

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

Clock

XTAL

Output

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

input through the EXTAL pin.

EXTAL

Input

CAC

CACREF

Input

Input pin for the clock frequency accuracy measurement circuit.

Operating mode control

Input

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

pins must not be changed during operation.

System control

RES#

Input

Reset pin. This MCU 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

FINED

I/O

FINE interface pin.

TRST#

Input

Pins for the on-chip emulator. When the EMLE pin is driven

high, these pins are dedicated for the on-chip emulator.

TMS

Input

TDI

Input

TCK

Input

TDO

Output

Interrupt

NMI

Input

Non-maskable interrupt request pin

IRQ0 to IRQ15

Input

Maskable interrupt request pins

Multi-function timer pulse

unit 3
