Transmission device, reception device, and communication system

A transmission device configured to communicate with a reception device via a control data bus, the transmission device comprising:

• a generation unit configured to generate an interrupt (IBI;
• In-Band Interrupt) request;
• and
• a transmission section configured to:
• issue the interrupt request in an SDR (Standard Data Rate) mode;
• and
• transmit transmission data to the reception device via the control data bus, wherein
• the interrupt request includes at least an identification bit to identify a type of the transmission data, an information bit for the transmission data, and the transmission data,
• the type of the transmission data indicates whether the transmission data is raw data or data obtained based on a data processing operation,
• the transmission device is further configured to communicate with the reception device via the control data bus in a communication standard of I3C (Improved Inter Integrated Circuit),
• the interrupt request includes at least MDB (Mandatory Data Byte) including the identification bit, and a header including the information bit and a change bit to change the type of the transmission data,
• the interrupt request further includes, as the transmission data, transmission data of a type corresponding to the change bit, and
• the transmission section is further configured to transmit the transmission data of the type corresponding to the change bit to the reception device via the control data bus based on the issued interrupt request.

A reception device configured to communicate with a transmission device via a control data bus, the reception device comprising:

• a reception unit configured to receive an interrupt (IBI;
• In-Band Interrupt) request (DA/R) from the transmission device via the control data bus, wherein the interrupt request is issued by the transmission device in an SDR (Standard Data Rate) mode;
• and
• a transmission section that configured to transmit Acknowledge (ACK) or NACK to the transmission device via the control data bus based on a reception result of the IBI request (DA/R), wherein
• the IBI request (DA/R) includes at least an identification bit to identify a type of transmission data transmitted by the transmission device via the control data bus, an information bit for the transmission data, and the transmission data,
• the type of the transmission data indicates whether the transmission data is raw data or data obtained based on a data processing operation,
• the reception device is further configured to communicate with the transmission device via the control data bus in a communication standard of I3C (Improved Inter Integrated Circuit),
• the interrupt request (DA/R) includes at least MDB (Mandatory Data Byte) including the identification bit, a header including the information bit, and the transmission data, and
• the transmission data is transmitted by the transmission device to the reception device via the control data bus based on the issued IBI request.

A communication system, comprising:

• a control data bus;
• a transmission device;
• and
• a reception device, wherein the transmission device and the reception device are configured to communicate via the control data bus, the transmission device including:
• a generation unit configured to generate an interrupt (IBI;
• In-Band Interrupt) request;
• and
• a transmission section configured to:
• issue the interrupt request in an SDR (Standard Data Rate) mode;
• and
• transmit transmission data to the reception device via the control data bus, wherein
• the interrupt request includes at least an identification bit to identify a type of the transmission data, an information bit for the transmission data, and the transmission data,
• the type of the transmission data indicates whether the transmission data is raw data or data obtained based on a data processing operation,
• the transmission device is further configured to communicate with the reception device via the control data bus in a communication standard of I3C (Improved Inter Integrated Circuit),
• the interrupt request includes at least MDB (Mandatory Data Byte) including the identification bit, a header including the information bit, and the transmission data, and
• the transmission section is further configured to transmit the transmission data to the reception device via the control data bus based on the issued interrupt request.
