Only 3 bytes (PDU_EM_LL_SIZE_MAX) is required for empty PDU transmission, but in case of Radio ISR latency if rx packet pointer is not setup then Radio DMA will use previously assigned buffer which can be this empty PDU buffer. Radio DMA will overrun this buffer and cause memory corruption. Any detection of ISR latency will not happen if the ISR function pointer in RAM is corrupted by this overrun. Increasing ISR latencies in OS and CPU usage in the ULL_HIGH priority if it is same as LLL priority in Controller implementation then it is making it tight to execute Controller code in the tIFS between Tx-Rx PDU's Radio ISRs.
