8-bit â 1 (N-channel open-drain output structure, can be used as PWM

output pins, INT input pins, A-D input pin)

8-bit â 1 (CMOS input/output structure, however, N-channel open-drain

output structure, when P11âP14 are used as multi-master I2C-BUS inter-

face, can be used as OSD output pin, A-D input pins, INT input pin, multi-

master I2C-BUS interface)

8-bit â 1 (P2 is CMOS input/output structure, however, N-channel open-

drain output structure when P20 and 21 are used as serial output, can be

used as serial input/output pins, timer external clock input pins, OSD clock

input/output pin, sub-clock input/output pins)
