An interface couples a controller to a physical layer (PHY) block, where the interface includes a set of data pins comprising transmit data pins to send data to the PHY block and receive data pins toreceive data from the PHY block. The interface further includes a particular set of pins to implement a message bus interface, where the controller is to send a write command to the PHY block over themessage bus interface to write a value to at least one particular bit of a PHY message bus register, bits of the PHY message bus register are mapped toa set of control and status signals, and the particular bit is mapped to a recalibration request signal to request that the PHY block perform a recalibration. 接口将控制器耦合到物理层(PHY)块，其中，该接口包括一组数据引脚，该组数据引脚包括发送数据引脚和接收数据引脚，该发送数据引脚用于向PHY块发送数据，该接收数据引脚用于从PHY块接收数据。接口还包括特定的一组引脚，其用于实现消息总线接口，其中，控制器用于在消息总线接口上向PHY块发送写入命令，以将值写入PHY消息总线寄存器的至少一个特定位，PHY消息总线寄存器的位被映射到一组控制和状态信号，并且该特定位被映射到重新校准请求信号以请求PHY块执行重新校准。
