get_burst_length()

This nonblocking procedure gets the burst_length field for a transaction that is uniquely
identified by the transaction_id field previously created by either the

create_write_transaction()

or

create_read_transaction()

procedure.

Note

The burst_length field is the value that appears on the AWLEN and the ARLEN protocol
signals. The number of data phases (beats) in a data burst is the burst_length + 1.
