Abstract
A communications method is provided for performing a rational priority processing according to the urgency of an interrupt transmission when an interrupt transmission command is supplied while a multi-address communication or a multi-polling reception is performed. The priority order of the processings is decided based on whether the interrupt command requests a direct transmission or a memory transmission. When the interrupt is the direct transmission, the interrupt is given priority. When the interrupt is the memory transmission, the multi-address communication or the multi-polling reception is given priority. In the interrupt transmission requesting the memory transmission, after an original for the interrupt transmission is read out and stored in a memory, the multi-address communication or the multi-polling reception is continued, and after the communication is completed, the data of the original for the interrupt transmission stored in the memory is transmitted.
