一种通过菊花链通信总线和协议进行数据传输的装置
摘要：
提供了一种装置，其包括第一和第二连接节点以及通信电路。该通信电路被配置成在连接至这些连接节点的双向数据路径上传达单元的单元状态数据。该通信电路包括定向驱动电路系统，其配置成通过经由第一连接节点在双向数据路径的一个方向上向第一侧电路系统传达单元状态数据、以及响应于该双向数据路径有故障的指示而通过经由第二连接节点沿该双向数据路径的另一方向地向第二侧电路系统进行通信来在该双向数据路径上传达单元状态数据。该通信电路还包括配置成控制该定向驱动电路系统的通信协议电路。该装置可与双向数据路径中的其他类似装置串行连接。
摘要（英）：

An apparatus is provided that includes first and second connection nodes and a communication circuit. The communication circuit is configured to communicate cell-status data of a cell over a bidirectional data path connected to the connection nodes. The communication circuit includes directional drive circuitry configured to communicate the cell-status data over the bi-directional data path by communicating the cell-status data via the first connection node to first-side circuitry in the one direction of the bi-directional data path and, in response to an indication that the bi-directional data path is faulty, by communicating via the second connection node to second-side circuitry along the other direction of the bi-directional data path. The communication circuit also includes a communication-protocol circuit configured to control the directional drive circuitry. The apparatus may be connected in-series with other like apparatuses in the bi-directional data path.
