Abstract: A method for reading/writing a chip in a USB type-C cable comprises converting a read/write command into unstructured vendor defined message (UVDM) that is conforming to a USB power delivery specification. Such UVDM will be delivered to the chip via a type-C configuration channel interface. The chip analyzes the UVDM to acquire the read/write command and reads or modifies the content of a non-volatile memory in the chip according to the read/write command. Due to use of the type-C configuration channel interface, which is inherent in the USB type-C cable, to read/write the chip, it needs no extra interface which otherwise increases costs.

Abstract translation: 用于在USB C型电缆中读取/写入芯片的方法包括将读/写命令转换成符合USB功率传递规范的非结构化供应商定义消息（UVDM）。 这样的UVDM将通过C类配置通道接口传送到芯片。 该芯片分析UVDM以获取读/写命令，并根据读/写命令读取或修改芯片中的非易失性存储器的内容。 由于使用USB C型电缆固有的C型配置通道接口来读/写芯片，因此不需要额外的接口，否则会增加成本。
