PORTS
The four Ports (IR, COM, AUX, and General
Purpose) provide external access for serial data
and controls. The active IrCC encoder is routed
through the Output Multiplexer to either the IR,
COM, or AUX port. The General Purpose port
provides external access for controls that are
independent of the IrCC Block Control bits or the
Output Multiplexer.
