1 TPS65987D GPIO Events

The TPS65987D device from the Texas Instruments family of USB Type-C® and USB PD controllers provides a set of GPIO events to achieve desired system behavior. A developer may program custom behavior triggered by GPIO to enable new functionality, and even load modified device configurations using GPIO events functionality.

These firmware-based GPIO events are simple to configure using the provided GUI software tools. The core TI PD controller firmware is unchanged when using GPIO events which ensures reliability, USB PD compliance, and also eases and speeds up development. This application report describes the procedure for configuring GPIO events on the TPS65987D and provides some concrete examples.
