R/W
Description
1011 = 48 Mbps
1100 = 64 Mbps
1101 = 72 Mbps
1110 = 80 Mbps
1111 = 88 Mbps
Note: For 10Base-T, rate settings above 10Mbps are set to the default
value 0000 (Not limited).
Note: When multiple queue select enable is off (only 1 queue per port),
rate limiting applies only to priority 0 queue.
Port 1 PHY Special Control/Status, LinkMD (Offset 0x0510): P1SCSLMD
This register contains the port LinkMD control register for the switch port 1 function.

Vct result
[00] = normal condition
[01] = open condition has been detected in cable
[10] = short condition has been detected in cable
[11] = cable diagnostic test is failed

Vct enable
1 = the cable diagnostic test is enabled. It’ll be self-
cleared after VCT test is done
0 = it indicates the cable diagnostic test is
completed and the status information is valid for
