Bus communication enhancement based on identification capture during bus arbitration

A receiving device for receiving a datagram from a sending device via a bus, comprising:

• a bus interface;
• and
• a processing circuit configured to:
• capture a sending device address during bus arbitration,
• receive the datagram subsequent to the bus arbitration, the datagram including at least a register address and a payload,
• obtain an address region specific to the sending device within a register space of the receiving device based on the captured sending device address and the register address included in the datagram, and
• write the payload of the datagram to the register space according to the obtained address region.

A receiving device for receiving a datagram from a sending device via a bus, comprising:

• means for capturing a sending device address during bus arbitration;
• means for receiving the datagram subsequent to the bus arbitration, the datagram including at least a register address and a payload;
• means for obtaining an address region specific to the sending device within a register space of the receiving device based on the captured sending device address and the register address included in the datagram;
• and
• means for writing the payload of the datagram to the register space according to the obtained address region.

A processor-readable storage medium having one or more instructions which, when executed by at least one processor or state machine of a processing circuit of a receiving device for receiving a datagram from a sending device, cause the processing circuit to:

• capture a sending device address during bus arbitration;
• receive the datagram subsequent to the bus arbitration, the datagram including at least a register address and a payload;
• obtain an address region specific to the sending device within a register space of the receiving device based on the captured sending device address and the register address included in the datagram;
• and
• write the payload of the datagram to the register space according to the obtained address region.
