Abstract
Dynamically configurable routing logic coupled between physical I/O ports and special purpose I/O associated with functions within a panel ASIC is disclosed that provide different routing configurations between the physical I/O ports and the special purpose I/O. In one routing configuration, any special purpose output can be coupled to one or more physical I/O ports, providing flexibility to route any functional I/O to any physical I/O port. In a second routing configuration, any input signal on a physical I/O port can be coupled to one or more special purpose inputs. In a third routing configuration, the input signals on a number of physical I/O ports can be configured to independently assert a single special purpose input for interrupt triggering. The dynamically configurable nature of the routing logic allows routing to be changed on the fly.
