Abstract

A processing system includes a digital processing unit, one or more non-volatile memories configured to store a firmware to be executed by the digital processing unit, a diagnostic circuit configured to execute a self-test operation of the processing system in response to a diagnostic mode enable signal, and a reset circuit. The reset circuit is configured to perform a complex reset of the processing system by generating a first reset of the processing system in response to a given event and generating a second reset of the processing system once the self-test operation has been executed. The processing system is configured to set the diagnostic mode enable signal in response to the first reset, thereby activating execution of the self-test operation.
