Abstract
An integrated circuit comprising: an input terminal configured to receive a failure-event-signal representative of a failure event; a first output terminal configured to provide a first-failure-signal; and a second output terminal configured to provide a second-failure-signal; and a processing block configured to: set the first-failure-signal based on the failure-event-signal; and set the second-failure-signal, at a predetermined time interval after the first-failure-signal is set. The processing block further comprises a switch configured selectively, based on a received digital-error-signal to either: set the second-failure-signal based on a digital-counter-output-signal; or set the second-failure-signal based on an analogue-trigger-signal.
