Remote Loopback
R/W
= 1, Perform Remote loopback, as follows:
Port 1 (reg. 26, bit 1 = ‘1’)
Start: RXP1/RXM1 (port 1)
Loopback: PMD/PMA of port 1’s PHY
End: TXP1/TXM1 (port 1)
Port 2 (reg. 42, bit 1 = ‘1’)
Start: RXP2/RXM2 (port 2)
Loopback: PMD/PMA of port 2’s PHY
End: TXP2/TXM2 (port 2)
= 0, Normal Operation
