ERAD is a hardware module that can be configured to non-intrusively monitor and profile critical CPU buses and device events.

ERAD is a hardware module with enhanced bus comparators and system event counters and sits within the MCU bus architecture as shown in the overview diagram. ERAD on its own can generate system level interrupts and flags and can also feed into other peripherals such as the CLB (configurable logic block) for further enhancing the capabilities. For complete understanding of the relationship between these two modules, see the CLB documentation located in the device-specific TRM.
