AMBA_PV_OKAYIndicates that a normal access has been successful. It also indicates an exclusive access failure.
AMBA_PV_EXOKAYIndicates that either the read or write portion of an exclusive access has been successful.
AMBA_PV_SLVERRIndicates that the access has reached the slave successfully, but the slave returned an error condition to the originating master.
AMBA_PV_DECERRIndicates that there is no slave at the transaction address. This is typically generated by an interconnect component.
