Function

Connected to 2.2~4.5V power supply at KHz and MHz

version or 4.0 ~ 5.5V power supply at WIDE version.

Connected to 0V power supply.

Used to input a manual reset. When the pin goes "L",

the D-output ports and REMOUT-output port are initialized to

"L", and ROM address is set to address 0 on page 0.

For programming, this pin receives 12.5V programming

voltage.

4-bit input port.

STOP mode is released by "L" input of each pin.

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.

STOP mode is released by "L" input of each pin.

High current output port.

The output is in the form of C-MOS.

The state of large current on is "H".

Oscillator input. Input to the oscillator circuit and connection

point for ceramic resonator.

Internal capacitors available at KHz version.

A feedback resistor is connected between this pin and OSC2.

Connect a resonator between this pin and OSC1.
