Abstract
A data transfer method is executed to transit a three-state transmitting circuit from a high-impedance state into a data output state, transmit a preamble (dummy data) onto a bus, and sequentially transmit the essential data. The shortening of a waveform caused in the first data piece after the transition from the high-impedance state into the data output state is executed against the preamble and no shortening of a waveform is not brought about in the essential data subsequent to the preamble. This makes it possible to exclude the limitation on speeding up the data transfer imposed by the shortening of the waveform.
