Can a master change the control signals for different transactions in a locked sequence?

Applies to: AXI

Answer

It is recommended that a master should not change AxPROT or AxCACHE during a sequence of locked accesses. This restriction ensures that the full locked sequence (including the unlocking transaction) is seen by appropriate components within the system.
