Abstract: A reconciliation module for a node of a multidrop bus network, the node comprising a MAC module and a PHY module, the reconciliation module comprising circuitry configured to: receive data from the MAC module for transmission on the multidrop bus network via the PHY module at a transmit opportunity of the node; assert a sense signal on receipt of the data from the MAC module; and delay de-assertion of the sense signal after transmission of the data to facilitate the transmission of further data at the next transmit opportunity of the node.

Abstract: A reconciliation module for a node of a multidrop bus network, the reconciliation module comprising circuitry configured to: receive data sent from a MAC module of the node as part of a first attempt by the MAC module to transmit the data; assert a collision signal by default on receipt of the data from the MAC module to stop the MAC module from continuing to send the data; and control a sense signal to cause the MAC module to resend the data as part of a second transmission attempt such that the data may be transmitted on the multidrop bus network via a PHY module of the node at an upcoming transmit opportunity.

Abstract: Embodiments of a device and method are disclosed. In an embodiment, a physical layer (PHY) device that is compatible with the IEEE 802.3 standard and that utilizes carrier-sense multiple access with collision detection (CSMA/CD) for media access control to a shared media is disclosed. The PHY device includes a physical coding sublayer transmitter (PCS-TX), a physical medium attachment transmitter (PMA-TX), a physical coding sublayer receiver (PCS-RX), a physical medium attachment receiver (PMA-RX), and a media access priority manager configured to initiate transmission of an indication of a priority of a frame that is to be transmitted onto the shared media.
