µPD6708

2. IEBus OPERATION

2.1 Operation Overview

5

The µPD6708 is an IEBus interface CMOS LSI device.

The IEBus is a bus for a small-scale digital data transfer system designed to transfer data between electronic devices.

The µPD6708 is connected to a microcontroller incorporated in electronic equipment with a serial interface (SCK, SO,

SI pins). The data and commands required to transfer data with the host controller (microcontroller) are set via this serial

interface.

When the host controller transmits data to the µPD6708 via the serial interface, signals are output from the BUS pins

(BUS+ and BUS–). Data received from the BUS pins can be read by the host controller via the serial interface.
