Pin functions (1 of 4)

Function

Signal

I/O

Description

Power supply

VCC

Input

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

this pin to VSS by a 0.1-µF capacitor. The capacitor should be

placed close to the pin.

VCL

I/O

Connect this pin to the VSS pin by the smoothing capacitor used to

stabilize the internal power supply. Place the capacitor close to the

pin.

VSS

Input

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

VBATT

Input

Battery Backup power pin

Clock

XTAL

Output

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

through the EXTAL pin.

EXTAL

Input

XCIN

Input

Input/output pins for the sub-clock oscillator. Connect a crystal

resonator between XCOUT and XCIN.

XCOUT

Output

CLKOUT

Output

Clock output pin

Operating mode control

Input

Pin for setting the operating mode. The signal level on this pin must

not be changed during operation mode transition on release from

the reset state.

System control

RES

Input

Reset signal input pin. The MCU enters the reset state when this

signal goes low.

CAC

CACREF

Input

Measurement reference clock input pin

On-chip emulator

TMS

I/O

On-chip emulator or boundary scan pins

TDI

Input

TCK

Input

TDO

Output

TCLK

Output

Output clock for synchronization with the trace data

TDATA0 to TDATA3

Output

Trace data output

SWO

Output

Serial wire trace output pin

SWDIO

I/O

Serial wire debug data input/output pin

SWCLK

Input

Serial wire clock pin

Interrupt

NMI

Input

Non-maskable interrupt request pin

IRQn

Input

Maskable interrupt request pins

IRQn-DS

Input

Maskable interrupt request pins that can also be used in Deep

Software Standby mode
