11.2.2 Self-ID Packet Receive after Transmitting Ping Packet Ping
Regardless of s-ID store bit setting in the mode-control register (refer to 7.1), the device receives self-ID packet after a ping
packet transmitted and stores the data removing logical inverse section in the Asynchronous receive-FIFO.
