Abstract
A video controller has one or more shared pins coupled to respective configuration signals. The shared pins are also coupled to other devices external to the video controller. Responsive to a reset signal, the configuration signals are stored in a configuration register. At other times, the external devices can overcome the configuration signals such that the shared pins may be used for other operations of the video subsystem.
