So, per my understanding since the Main master support the hand-off of
the bus you accept all incoming MR, right? Or do you check all devices BCR?
I'm not sure what do you mean here. Mastership request(MR) is from secondary master
to current master. Current master can NACK this request if for example it comes from
wrong device. If it's ok, current master sends GETACCMST command and secondary master
may ACK or NACK this command. It it's acked, secondary master becomes current master.

Please let me know if something is unclear.

Sorry, it s not clear yet.
For instances there is a bus with several secondary master. If each of
them request the bus mastership (one at a time), will you accept all by
default? Because you can only accept only some of them.
