Abstract
In one embodiment, an integrated circuit ( ) has a contention detection circuit ( ) coupled to a tri-stateable output buffer ( ). The contention detection circuit ( ) provides a contention tri-state control signal ( ) to the tri-stateable output buffer ( ) in order to place it in a tri-stated condition when an external device ( ), such as a computer, supplies power to an input/output pad ( ) on the integrated circuit ( ). Thus, external and/or internal buffer contention is avoided when an external device ( ), such as a computer, supplies power to an input/output pad ( ) on the integrated circuit ( ).
