Switch Looopback MII
When set, transmissions from the switch fabric Port 0(External MII) are not
sent to the External MII. Instead, they are looped back into the switch
engine.
From the MAC viewpoint, this is effectively a FAR LOOPBACK.
If loopback is enabled during half-duplex operation, then the Enable Receive
Own Transmit bit in the
(MAC_RX_CFG_x)

This mode works even if the Isolate bit of the

Switch Collision Test MII
When set, the collision signal to the switch fabric Port 0(External MII) is
active during transmission from the switch engine.
It is recommended that this bit be used only when using loopback mode.

Current Speed/Duplex Indication
This field indicates the current speed and duplex of the Virtual PHY link.

SQEOFF
This bit enables/disables the Signal Quality Error (Heartbeat) test.
0: SQE test enabled
1: SQE test disabled
Virtual PHY Special Control/Status Register (VPHY_SPECIAL_CONTROL_STATUS)
This read/write register contains a current link speed/duplex indicator and SQE control.
