Description

Power supply

VCC, VSS

I Apply 2.7 V to 5.5 V to VCC pin and 0 V to VSS pin.

Analog power

supply

Reset input

AVCC,

AVSS

RESET

Power supply for the A/D converter. AVCC and AVSS should be

connected to VCC and VSS, respectively.

I Low active input pin. Driving this low resets the MCU.

CNVSS

Main clock input

Main clock output

CNVSS

XIN

XOUT

I Connect the CNVSS to VSS.

I Input/output pin for the main clock oscillator. Connect a ceramic

resonator or crystal oscillator between XIN and XOUT. (1) To apply

O an external clock, connect it to XIN and leave XOUT open. When

XIN is not used, connect XIN to VCC pin and leave XOUT open.

Sub clock input

Sub clock output

XCIN

XCOUT

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

O between XCIN and XCOUT.

Clock output

CLKOUT

INT interrupt input INT0 to INT5

NMI input

NMI

Key input interrupt KI0 to KI3

This pin outputs the clock having the same frequency as f1, f8, f32,

or fC.

Low active input pins for INT interrupt. INT2 is used to input Z-phase

of timer A.

I Low active input pin for NMI interrupt.

I Low active Input pins for the key input interrupt

Timer A

TA0OUT to

TA4OUT

I/O Timers A0 to A4 input/output pins

TA0IN to TA4IN

I Timers A0 to A4 input pins

I Input pin for Z-phase

Timer B

Three-phase motor

control timer

TB0IN to TB2IN

U,U,V,V,W,W

IDU, IDW, IDV, SD

I Timers B0 to B2 input pins

O Output pins for three-phase motor control timers

I Input pins for three-phase motor control timers

Real time clock
