If a mismatch is detected, this feature can change the status of an output pin or generate an interrupt so that the system can respond appropriately. To improve the usability as an online monitoring safety mechanism an efficient read back test can prioritize between safety-related and non-safety-related parts within a device. Safety related parts can be checked more frequently to considerably shorten failure detection time."/>
