Abstract
A communication control section is provided with a plurality of receiving channels (RXDA1 and RXDA2). An address separated by an address separating section constituting the RXDA1 is compared with a reference address denoting a token, and if the separated address corresponds thereto, an interruption is requested by an interruption processing section. An address separated by an address separating section constituting the RXDA2 is compared with a reference address denoting the station number of that particular station, and if the separated address corresponds thereto, the interruption is similarly requested. When the interruption has been requested, the processing of a CPU transfers from the processing of a main routine by a main routine processing section to an interruption processing by an interruption processing section.
