Abstract
Official abstract text for this publication.
A control chip includes a configurable pin and a control logic. The configurable pin is arranged for coupling a first pin and a second pin of a high-definition multimedia interface (HDMI) connector. The control logic is arranged for controlling the configurable pin to switch between a first operation mode and a second operation mode. The configurable pin serves as an input pin when operating in the first operation mode, and the configurable pin serves as an output pin when operating in the second operation mode. For example, the input pin is arranged for receiving a power supply signal derived from a +5V power signal received by the first pin, and the output pin is arranged for outputting a control signal for controlling hot plug detection (HPD).
First claim
Opening claim text (preview).
What is claimed is: 1. A control chip, comprising: a configurable pin, arranged for coupling to an external power pin and an external hot plug detect pin of a wired connection interface; and a control logic, arranged for controlling the configurable pin to switch between a first operation mode and a second operation mode; wherein the configurable pin serves as an input pin configured for receiving a power supply signal through the external power pin when operating in the first…
