Apparatus for dynamic deployment of pin functions on a chip

An apparatus for dynamic deployment of pin functions on a chip, the apparatus comprising:

• an input pin receiving unit, capable of integrating a plurality of pins and selecting pin functions according to a program;
• an output pin control unit, capable of issuing a control signal to the plurality of pins;
• and
• a signal control unit, controlled by the program and coupled to the input pin receiving unit and the output pin control unit so as to communicate therebetween;
• wherein the pin functions are designated by the user to select an output signal for each of the plurality of pins according to the program;
• wherein the input pin receiving unit comprises a plurality of multiplexers;
• and
• wherein the number of the multiplexers equals to half of the number of the pins plus one.
