E_LP_1 and E_LP_2 are the EMAC Receiver Last Packet registers for EMAC1 and
EMAC2, respectively. Writing to this register will clear all of its bits (as denoted by
RW*).

Transmit Fault.
Transmit Jabber Timeout.
E_NA_HUJ and E_NA_HUJ must be configured for this bit to function.
No Carrier.
Lost Carrier.
16+ Collisions.
Late Collision.
Collision Count.
Transmit collision count of the current frame. Resets after the frame is
transmitted. Increments with every collision of the current frame.
Reserved.

Receive FIFO State Machine State. (For test only.)
Receive Done OK from RX Buffer Manager.
Transmit Done OK from TX Buffer Manager.
0 = Unexpected transmit data request has not occurred during
1 = Unexpected transmit data request has occurred during current
0 = Jabber timer has not expired.
1 = Jabber timer has expired.
0 = carrier detected.
1 = No carrier (EMx_CRS pin never transitioned high) during frame
0 = Carrier was not lost during frame transmit.
1 = Carrier was lost (EMx_CRS pin transitioned low) at least once
0 = 16 or more collisions have not occurred during frame transmit.
1 = 16 or more collisions have occurred during frame transmit.
