ABSTRACT:
An integrated circuit300includes a functional circuit310and a diagnostic circuit330. The integrated circuit includes a signal interface controller320operable to monitor a signal associated with at least one of the functional circuit and the diagnostic circuit to control selective communication of a diagnostic signal and a functional signal for communication across a signal interface in dependence upon the monitored signal. A further integrated circuit has a signal interface providing a communication path and communicates a functional signal having at least one multi-bit value in which at least one bit is replaced by data of a diagnostic signal.
