Mode 3:
Loopback through the cable (LB1=1, LB0=1 in TCR)
The packets are transmitted via the MAU onto the network and RTL8009 receives all
incoming packets (not only the MAU-loopbacked Tx data) in the meantime.

Alignment of the Reception FIFO
The reception FIFO is an 8-byte ring structure. The first received byte is put at location zero.
When the location pointer goes to the end of the FIFO, it wraps to the beginning of the FIFO and
overwrites the previous data. At the end of the packet reception, the FIFO contents are in the
"order" (from the ring structure's view) as shown below.
(1) CRC enabled (CRC bit in TCR=0)
s
1-byte received packet data
s
4-byte CRC
s
1-byte lower byte count
s
1-byte upper byte count
s
1-byte upper byte count
(2) CRC disabled (CRC bit in TCR=1)
s
5-byte received packet data
s
1-byte lower byte count
s
1-byte upper byte count
s
1-byte upper byte count
6.6.2. To Implement Loopback Test
(1) To verify the integrity of data path
s
set RCR=00h to accept physical packet
s
set PAR0-5 to accept packet
s
set DCR=40h (8-bit slot) or 43h (16-bit slot)
s
set TCR=02h, 04h, 06h to do loopback test 1, 2, 3 respectively
s
set CRC enabled (CRC=0 in TCR)
s
clear ISR
s
tx a packet and check ISR
s
check FIFO after loopback
Note: Loopback mode 3 is sensitive to the network traffic, so the values of FIFO may be not
correct.
(2) To verify CRC logic
q
Select a loopback mode (e.g. mode 2) to test
A. To test CRC generator
s
set RCR=00h to accept physical packet
