A method for providing an early packet termination such that prior to the
complete transmission of the number of cells specified in the first cell
of a packet, a crossbar connection is released. The act of releasing the
connection is triggered on recognition of an End of Packet bit (EOP) set
in any cell of the stream. The feature can be enabled, for example, by a
specific act of setting a register bit, connecting a pin to Vcc or ground
or some other intentional act. The feature will default to the inactive
state upon reset.
