4 PD Controller Customization by GPIO Events

This section shows how TI PD controller GPIO events can be used in a system to alter system behavior while keeping the core firmware same. A Barrel Jack Event is used as example to show how a docking application can initiate power role swap when external power is connected to the system. Removal of the external power would generate PD traffic to reverse the power role swap and put the system back to original state.
