5.6.5.9.2. BIST Loopback Mode

In the BIST loopback mode, the BIST controllers multiplex the BIUS and BIUM interfaces and sets up the transfer by performing register writes/reads to the BIUS interface and by writing/reading required TRB/data/command/event data on the BIUM interface.

For data, there is an option to select the data pattern and compare the received data with the expected data and indicate loopback pass/fail.
