Abstract:
There is provided a communication system including a transmission interface, a master device and a slave device. The transmission interface includes a TR/ACK channel configured to transmit a trigger signal and an acknowledge signal and a DA channel configured to transmit a normal data or a simplified data. The master device sends the trigger signal via the TR/ACK channel before data transmission begins. The slave device sends the normal data or the simplified data to the master device via the DA channel after receiving the trigger signal.
