Abstract

A key scanning circuit scans a key matrix circuit to generate key input data as for key operations. A remote control decoder decodes an encoded signal, which has been output from a remote control transmitter and received by a remote control receiving circuit, to generate remote control data. A transmission register selectively stores either the key input data or remote control data. By transmitting the data stored in the single transmission register, it is possible to transmit any one of the key input data and remote control data to the microcomputer.
