get_read_addr()
This nonblocking procedure returns the actual address addr a particular byte in a read data
transaction. It also returns the maximum number of bytes (dynamic_size) in the read data phase
(beat). It is used in a slave test program as a helper procedure to return the address of a data byte
in the slave memory
.
