Abstract:

A microcontroller has a central processing unit and a plurality of peripheral units and a plurality of port bit circuits provided through at least one input/output port. At least one port bit circuit of the plurality of port bit circuits is not connected to an external pin and the at least one port bit circuit is configurable to route a signal received at the port bit circuit to a selected peripheral of the microcontroller.
