Abstract

Data fed in through a PIO or UART is first converted into IrDA-protocol-conforming data by a CPU executing a software program stored in a ROM, and the resulting data is then fed by way of a bus to a modulation circuit so as to be modulated. A signal fed in to a demodulation circuit is first demodulated to restore IrDA-protocol-conforming data, and the demodulated data is then converted back into its original data by the CPU executing the software program stored in the ROM. The restored data is fed by way of the bus to the PIO or UART.
