Abstract
A peripheral integrated circuit (IC) device for providing support to a data processing IC device. The peripheral IC device comprises a fault detection component arranged to detect an occurrence of fault conditions within the data processing IC device. The peripheral IC device further comprises a safe state control component. Upon detection of a fault condition occurring within the data processing IC device by the fault detection component, the safe state control component is arranged to cause at least one I/O cell of the data processing IC device to be configured into at least one scan-chain, and cause at least one predefined control signal to be scanned into the at least one scan-chain to configure the at least one I/O cell into a state corresponding to the predefined control signal.
