Arbitration in a single bus mode only grants one master access to the bus,
whereas in multiple bus mode more than one master can have transactions
executing in parallel. The arbitration mechanism of the multiple bus mode is
adapted to meet the requirements of the single bus mode in FLEXBUS. This is
done by using a distributed arbitration mechanism in the single bus mode, in
which one of the arbiters acts as a virtual master that is regulated by the other
arbiter. For example, in Fig. 8.35 , if Arbiter2 receives a transfer request from a
master on AHB2, it immediately sends a request to Arbiter1 using busreq_AHB2
andlock_AHB2 signals.

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.
