Description

(Port F)

8-bit output port

and large current

(12mA) N-channel

open drain output.

Lower 4 bits are

midium drive voltage

(12V); upper 4 bits

are 5V drive.

(8 pins)

8-bit PWM output.

(4 pins)

I2C bus interface transfer clock I/O.

(2 pins)

8-bit PWM output.

I2C bus interface transfer data I/O.

(2 pins)

8-bit PWM output.

(Port G)

1-bit I/O port.

External interruption request input.

Active at the falling edge.

Connects a crystal for system clock oscillation. When a clock is

supplied externally, input it to EXTAL pin and input a reversed phase

clock to XTAL pin.

System reset; active at Low level.

OSD display clock oscillation I/O. Oscillation frequency is determined

by the external L and C.

No connected.

Positive power supply.

GND. Connect two Vss pins to GND.
