12.8.15 External Physical Layer LSI
The pin name, usage, and type may differ according to each of external physical layer LSI. Check
and confirm the specifications of it before connecting to this LSI.
12.8.16 Operation at the Bus Reset Reception
When a bus reset is received from the host, there will be a defect in the operation described below.
When the first bus reset from the host completes, and then the second bus reset is received without
following bus accesses of SOF or data transfer, the second bus reset will not be received
successfully (shown in case 2 in figure 12.19).
Note: Since the successive bus resets are not normally required, the bus reset does not occur
In order to detect the bus reset correctly, even in the case 2, follow the procedure shown in figure
12.20.
