11.2.1 Self-ID Packet Receive at Bus Reset Process
This section explains the receiving process of Self-ID packet.
The MB86617A device is capable of receiving self-ID packets that each mode transmit in the self-identity stage of bus reset
process. When ‘1’ is written to the s-ID store bit of mode-control register (refer to 7.1), the self-ID packet in the bus reset
process can be received and the data removing the logical inverse section is stored in the Asynchronous receive-FIFO and
Asynchronous transmit -FIFO (512 bytes maxixum). When the number of total data exceeds 512 bytes, the overflown data
are discarded.
Bus reset force-clears FIFO for Asynchronous receiving and FIFO for Asynchronous transmitting to store Self-ID packet.
