Signal Descriptions
Packet being received had a bad FCS
L64381 detected a PLL error.
If the L64381 does not read the failing packet out on the
Bus Interface and the packet resides in the Receive
FIFO, the L64381 does not flush the Receive FIFO. The
L64381 updates the appropriate Statistics Counters and
waits for the external device to remove the data. When
the packet drains completely, the L64381 asserts
ABORT_OUT with EOP to the external device for errored
packet signaling.
When data is being written to the Transmit FIFO on the
Bus Interface, if the current packet being written is also
being transmitted to the Network Interface, and the L64381
detects a failing condition on the Network Interface, the
L64381 asserts the ABORT_OUT signal, updates the
appropriate Statistics Counters based on the failing con-
dition, and flushes the current packet from the Transmit
FIFO. The failing condition is one of the following:
L64381 detected a late collision
L64381 detected excessive collisions
L64381 detected a collision, and it is not in autostore
64-byte mode
L64381 detected a Transmit FIFO underrun error
L64381 detected an invalid BYTE_VALID[3:0]
combination
AI_FCS_IN
Autoinsert FCS
The L64381 latches in AI_FCS_IN when SOP and
WRITE_IN_PKT are both asserted. Assertion of this
input while SOP is asserted causes the L64381 to auto-
matically calculate and insert the CRC value from the
packet data into the FCS field of the Ethernet packet. If
this input is deasserted when SOP and WRITE_IN_PKT
are both asserted, then the data provided for transmis-
sion must contain the FCS field.
Input
BUF_AVAIL
Buffer Available
The L64381 asserts this signal in response to the
assertion of STROBE when the Transmit FIFO has
enough empty space available to store data from a bus
transfer. The FIFO is deemed to have enough space if it
