LSI Specification MB86617A

11.2.2Self-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.
