ERROR DETECTION ON INTEGRATED CIRCUIT INPUT/OUTPUT PINS

A method for detecting error on an input/output (IO) pin of an integrated circuit includes using the input/output pin of the integrated circuit in a first mode by receiving or sending a first value as analog data or digital data. The input/output pin is toggled in a test mode after each instance of...

Zusammenfassung:	A method for detecting error on an input/output (IO) pin of an integrated circuit includes using the input/output pin of the integrated circuit in a first mode by receiving or sending a first value as analog data or digital data. The input/output pin is toggled in a test mode after each instance of using the input/output pin in the first mode. The test mode includes providing a second value disparate from the first value during a set time after using the input/output pin in the first mode, receiving back during the set time a resulting value based on providing the second value, measuring the resulting value, and identifying an error on the input/output pin of the integrated circuit based on the measured resulting value.
