Communication of a diagnostic signal and a functional signal by an integrated circuit |
摘要 |
An integrated circuit 300 includes a functional circuit 310 and a diagnostic circuit 330. The integrated circuit includes a signal interface controller 320 operable 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. |
