    • An enumeration technique is provided that requires no pre-assignment of addresses to slave devices connected through P2P links to a host device. With regard to any P2P link between devices, one device has a master interface and the remaining device has a slave interface. To distinguish between the master and slave interfaces, a master/slave status bit may be used. Each P2P link has a link ID that may be concatenated with the status bit for a corresponding interface (slave or master) to form a node ID. The host device receives a unique concatenated address from each slave device that represents a concatenation of the node ID for the slave and the node ID for any intervening interfaces between the slave device and the host device. The host device then assigns a unique Cartesian address to each slave device.
    • 提供了一种枚举技术,其不需要将通过P2P链接连接到主机设备的从设备的地址预先分配。 关于设备之间的任何P2P链路,一个设备具有主接口,其余设备具有从接口。 为了区分主从接口,可以使用主/从状态位。 每个P2P链路具有可以与相应接口(从属或主机)的状态位连接以形成节点ID的链路ID。 主设备从每个从设备接收代表从设备的节点ID的级联和从设备与主设备之间的任何介入接口的节点ID的唯一的级联地址。 然后,主机设备为每个从设备分配唯一的笛卡尔地址。
