Abstract
A microcontroller includes a general purpose input/output (GPIO) port having a plurality of bits coupled to a plurality of external pins; a first set of registers for providing at least one of first control and data input/output functionality of the GPIO port; a second set of registers for providing at least one of second control and data input/output functionality of the GPIO port; and a multiplexer and associated select register for controlling the multiplexer to control said GPIO port through either said first or second register set.
