Abstract: PROBLEM TO BE SOLVED: To provide a system and a method to designate the functions of one or more semiconductor device pins. SOLUTION: A semiconductor device pin 500 is designated in a programmable way. The pin 500 includes a combination of a programming port 100 which receives plural pin designating instructions, a configuration logic 300 which is connected to the port 100 and stores those pin designating instructions, a selection logic 400 which is connected to the port 100 and selects a function to designate at least one pin, and at least one pin which is connected to the logic 400 and designated in a programmable way to execute one of plural I/O functions.
