Description

Power supply

Oscillation output pin

Power supply

Oscillation input pin

Reset input pin

Active ”L”

Internal pull-high resistors are connected between

this pin and the VCC pins.

Analog to digital pin

Chip select

Serial input pin

The clock is read twice with a 2MHz sampling rate

in order to judge if the signal is a noise or not.

Serial output pin

During the Reset condition, this pin is in

high-impedance state.

Serial clock input pin

The clock is read twice with a 2MHz sampling rate

in order to judge if the signal is a noise or not.

Pull-down power supply

Supplies voltage to Pull-down resistors

Grid/Port output pins

This pin acts as either a Grid Output Pin or as an

Ordinary Port Terminal.

During the reset condition, this pin is set to VEE

via a pull-down resistor.

Grid/Segment output pins

This pin acts as either a Grid Output Pin or as an

Segment Output Pin.

During the reset condition, this pin is set to VEE

via a pull-down resistor.

Segment output pin

During the reset condition, this pin is set to VEE

via a pull-down resistor.
