Description

Power supply

VCC

Input

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

VSS through a 0.1-μF capacitor. The capacitor should be placed close to the

pin.

VCL

I/O

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

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

VSS

Input

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

VBATT

Input

Backup power supply 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

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

Interrupt

NMI

Input

Non-maskable interrupt request pin

IRQ0 to IRQ12,

IRQ14, IRQ15

Input

Maskable interrupt request pins

KINT

KR00 to KR07

Input

Key interrupt input pins.

A key interrupt (KINT) can be generated by inputting a falling edge to the key

interrupt input pins.

On-chip debug

TMS

I/O

On-chip emulator or boundary scan pins

TDI

Input

TCK

Input

TDO

Output

SWDIO

I/O

Serial wire debug data input/output pin

SWCLK

Input

Serial wire clock pin

SWO

Output

Serial wire trace output pin

Battery Backup

VBATWIO0 to

VBATWIO2

I/O

Output wakeup signal for the VBATT wakeup control function.

External event input for the VBATT wakeup control function.

GPT

GTETRGA,

GTIV

Input

Hall sensor input pin V

GTIW

Input

Hall sensor input pin W

GTOUUP

Output

3-phase PWM output for BLDC motor control (positive U phase)

GTOULO

Output

3-phase PWM output for BLDC motor control (negative U phase)

GTOVUP

Output

3-phase PWM output for BLDC motor control (positive V phase)

GTOVLO

Output

3-phase PWM output for BLDC motor control (negative V phase)

GTOWUP

Output

3-phase PWM output for BLDC motor control (positive W phase)

GTOWLO

Output

3-phase PWM output for BLDC motor control (negative W phase)
