Output

Each can be set and reset independently.

The output is the structure of N-channel-open-drain.

4-bit I/O port. (Input mode is set only when each of them output "H".)

In outputting, each can be set and reset independently(or at once.)

The output is in the form of C-MOS.

Pull-up resistor and STOP release mode can be respectively selected

as masked option for each pin. (It is released by "L" input at STOP)

Oscillator input. Input to the oscillator circuit and connection point for

ceramic resonator.

Internal capacitors available at kHz version.

A feedback resistor is internally connected between this pin and OSC2.

Connect a resonator between this pin and OSC1.

High current output port. The output is in the form of CMOS.

The state of large current on is "H".
