Description

Main clock

input

XIN

VCC1

I/O pins for the main clock generation circuit. Connect a ceramic

resonator or crystal oscillator between XIN and XOUT (3). To use

the external clock, input the clock from XIN and leave XOUT open.

Main clock

output

XOUT

VCC1

Sub clock input XCIN

VCC1

I/O pins for a sub clock oscillation circuit. Connect a crystal

oscillator between XCIN and XCOUT (3). To use the external clock,

input the clock from XCIN and leave XCOUT open.

Sub clock

output

XCOUT

VCC1

BCLK output (2) BCLK

VCC2

Outputs the BCLK signal.

Clock output

CLKOUT

VCC2

The clock of the same cycle as fC, f8, or f32 is outputted.

INT interrupt

input

INT0 to INT2

VCC1

Input pins for the INT interrupt.

NT3 to INT5

VCC2

NMI interrupt

input

NMI

VCC1

Input pin for the NMI interrupt. Pin states can be read by the P8_5

bit in the P8 register.

Key input

interrupt input

KI0 to KI3

VCC1

Input pins for the key input interrupt.

Timer A

TA0OUT to

TA4OUT

I/O

VCC1

These are timer A0 to timer A4 I/O pins. (however, output of

TA0OUT for the N-channel open drain output.)

TA0IN to

TA4IN

VCC1

These are timer A0 to timer A4 input pins.

VCC1

Input pin for the Z-phase.

Timer B

TB0IN to

TB5IN

VCC1

These are timer B0 to timer B5 input pins.

Three-phase

motor control

output

U, U, V, V,

W, W

VCC1

These are Three-phase motor control output pins.

Serial interface CTS0 to

CTS2

VCC1

These are send control input pins.

RTS0 to

RTS2

VCC1

These are receive control output pins.

CLK0 to

CLK4

I/O

VCC1

These are transfer clock I/O pins.

RXD0 to

RXD2

VCC1

These are serial data input pins.

SIN3, SIN4

VCC1

These are serial data input pins.

TXD0 to

TXD2

VCC1

These are serial data output pins. (however, output of TXD2 for the

N-channel open drain output.)

SOUT3,

SOUT4

VCC1

These are serial data output pins.

CLKS1

VCC1

This is output pin for transfer clock output from multiple pins

function.

I2C mode

SDA0 to

SDA2

I/O

VCC1

These are serial data I/O pins. (however, output of SDA2 for the N-

channel open drain output.)

SCL0 to

SCL2

I/O

VCC1

These are transfer clock I/O pins. (however, output of SCL2 for the

N-channel open drain output.)
