Abstract
A data communication method between a master system and multiple slave systems using a serial input/output interface. The master system connects a communication path to a corresponding slave system, and transmits a message and simultaneously receives a message from the slave system during an assigned communication time. When the transmission of the message ends, the master system transmits a final message and when a final acknowledgement message is received, performs a service for the next slave system. Meanwhile, the slave system receives a message transmitted by the connection of the communication path and simultaneously transmits a message to the master system. Further, when a final message is received, the slave system transmits a final acknowledgement message to the master system. Thus, the effective communication between point-to-multipoint can be achieved.
