There are three Dual-Clock Comparators (DCC0, DCC1, and DCC2) on the device. All three DCCs are only accessible through CPU1. The DCC module is used for evaluating and monitoring the clock input based on a second clock, which can be a more accurate and reliable version. This instrumentation is used to detect faults in clock source or clock structures, thereby enhancing the system's safety metrics.
