Parking
If no master is currently requesting the slave port, the slave port is parked. The slave port
parks always to the most recently requesting master (park-on-last). When parked on the last
master, the slave port is passing that master’s signals through to the slave bus. When the
master accesses the slave port again, no other arbitration penalties are incurred except that
a one clock arbitration penalty is incurred for each access request to the slave port made by
another master port. All other masters pay a one clock penalty.
