It ist very strange but there is no possibility to generate for example the TRAP event from DSD unit (XMC4500). Typically, DSD can monitor the current levels with selected low and upper boundaries. For this reason the Auxiliary Filter is here in parallel to the Main Filter. Excellent! But the only way to react is the NVIC, so the normal software interrupt! Is it not better to connect such a critical event to the ERU unit to generate for example the TRAP for CCU? This is a HARDWARE BUG!
