ABSTRACT:
A technique for protecting an electronic system having a programmable input/output interface from erroneous operation due to static electricity includes the steps of: (a) setting an internal timer for continuously resetting a program state of the input/output interface at a predetermined time interval; (b) storing a present program state of the input/output interface after setting the timer; (c) resetting the stored program state of the input/output interface when a value of a driven timer corresponds to a value of the set timer after storing the present program state of the input/output interface; (d) repeatedly resetting the program state of the input/output interface by driving again the timer after resetting the program state of the input/output interface.
