Abstract

An apparatus has processing circuitry to perform data processing in one of two or more operating states associated with different levels of privilege. At least one operating state holding element holds a state indication indicating a current operating state of the processing circuitry. In response to a transition of a reset signal from a first value to a second value for triggering a reset of the processing circuitry, the at least one operating state holding element resets the state indication to indicate a default operating state other than a most privileged operating state of the two or more operating states.
