  • Special function micro controller integrated circuit programmed to selectively perform one of at least two different and unrelated functions
    Patent number: 5428813
    Abstract: To maximize the usefulness of micro controllers, a single micro controller is programmed to selectively perform multiple functions based on code segments stored within the micro controller, so that a single programmed micro controller may be used to perform one of a number of different tasks depending upon where the micro controller is used. A pin of the micro controller is adapted to receive a logical signal to which the code responds and selects the function to be performed by the micro controller. The programming of a micro controller to perform multiple functions takes advantage of the full capacity of the micro controller and reduces the numbers of micro controllers that must be inventoried to satisfy the required functions.
