Abstract
A microcomputer interface arrangement includes a microcomputer having I/O ports coupled to individual interface units. A fault detection circuit detects a fault in an interface unit, interrupts the microcomputer and inverts the input state of the faulty unit without affecting the output states so that the faulty unit can be identified by the microcomputer by reading inputs of the interface units.
