Input

External input pin to FRC capture unit.

(Port G)

8-bit input port.

(8 pins)

(Port H)

N-ch open drain output of middle tension proof (12V) and high current

(12mA).

(8 pins)

Remote control receiving circuit input pin.

14-bit PWM output pin.

Timer/counter, 32kHz oscillation adjustment output

pin.

Input pin to request external interruption and non

maskable interruption. Active when falling edge.

Serial clock (CH1) I/O pin.

Serial data (CH1) output pin.

Serial data (CH1) input pin.

(Port I)

7-bit I/O port.

I/O port can be

specified by the

bit unit.

(7 pins)

(Port J)

8-bit I/O port. Function as standby release input can be specified by

the bit unit. I/O can be specified by the bit unit.

Connecting pin of 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.

Connecting pin of crystal oscillator for 32kHz timer clock. When used

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

(Feedback resistor is not removed.)
