Description

(Port G)

8-bit input port.

(8 pins)

External input to FRC capture unit.

(2 pins)

(Port H)

N-ch open drain output of medium drive voltage (12V) and large current

(12mA).

(8 pins)

Remote control reception circuit input.

(Port I)

7-bit I/O port.

I/O port can be

set in a unit of

single bits.

(7 pins)

14-bit PWM output.

Timer/counter, 32kHz oscillation adjustment output.

Input to request external interruption and non

maskable interruption. Active at the falling edge.

Serial clock I/O (CH1).

Serial data output (CH1).

Serial data input (CH1).

(Port J)

8-bit I/O port. I/O and standby release input function can be set in a

unit of single bits.

Connnects a crystal oscillator for system clock. When supplying the

external clock, input the external clock to EXTAL pin and input

opposite phase clock to XTAL pin.

Connects a crystal oscillator for 32kHz timer/counter clock. When used

as event counter, input to TEX pin and leave TX pin open.

System reset; active at Low level.

Test mode pin. Always connect to GND.

Positive power supply of A/D converter.

Reference voltage input of A/D converter.

GND of A/D converter.

Positive power supply.

GND. Connect both Vss pins to GND.
