Abstract: Communication channels among a connector port module, a debug interface module, and a power communication interface module may be established. Each of these elements may be part of a system-on-chip. The power communication interface module may be coupled to an integrated circuit, such as a power management integrated circuit. The connector port module may be coupled to a connector, in which the connector may facilitate connections between the PCD and one or more external devices, such as a testing/debugging device. The connector may comprise an SD connector. The connector may be monitored for a device present signal. If a device present signal has been detected, then it may be determined if a valid access code has been received for allowing access to communications within the PCD. If a valid access code is received, then a command may be issued to relinquish control of the integrated circuit from a master processor.

Abstract translation: 可以建立连接器端口模块，调试接口模块和电力通信接口模块之间的通信信道。 这些元件中的每一个可以是片上系统的一部分。 电力通信接口模块可以耦合到诸如电力管理集成电路的集成电路。 连接器端口模块可以耦合到连接器，其中连接器可以有助于PCD与一个或多个外部设备（例如测试/调试设备）之间的连接。 连接器可以包括SD连接器。 可以监视连接器以用于设备当前信号。 如果已经检测到设备呈现信号，则可以确定是否已经接收到有效的访问代码以允许访问PCD内的通信。 如果接收到有效的访问代码，则可以发出命令来放弃来自主处理器的集成电路的控制。
