Reserved for future use: This bit is currently undefined.
Management software should not examine the state of this bit.
Packet Compression Done: If packet compression is utilized, this bit informs the user
that compression was performed, i.e., the packet was long enough to require
compression.
RIC2A Address (5:0): This address is defined by the user and is supplied when writing
to the RIC2A Address Register. It is used by hub management software to distinguish
between RIC2As in a multi-RIC2A system.
Port Address: This field defines the port which is receiving the packet.
Clean Receive: This bit is asserted provided no collision activity occurs during
repetition of the source and destination address fields, and the packet is of sufficient
size to contain these fields.
Collision: If a receive or transmit collision occurs during packet repetition the collision
bit is asserted.
Frame Alignment Error: This bit is asserted if a Frame Alignment Error occurred in
the repeated packet.
CRC Error: This bit is asserted if a CRC Error occurred in the repeated packet.
This status flag should not be tested if the COL bit is asserted since the error may be
simply due to the collision.
