Capability:

Contains two octets which define the capability of the PHY interface. The SAPI

board has 0x21 & 0x0C programmed into octets 1 & 2 respectively. The

capabilities include:

1. TxRef, =1 when this interface supports the TxRefB UTOPIA signal.

2. RxRef, =1 when this interface supports the RxRefB UTOPIA signal.

3. TxClav, =1 when this interface supports the TxClav UTOPIA signal.

4. RxClav, =1 when this interface supports the RxClav UTOPIA signal.
