The DM9801 supports half Duplex Operation only. This bit is
permanently set to 1
Reserved:
Write as 0, ignore on read
MII Frame Preamble Suppression:
1=PHY will accept management frames with preamble suppressed
0=PHY will not accept management frames with preamble suppressed
Auto-negotiation Complete:
The DM9801 does not support this function. This bit is
permanently set to 1
Remote Fault:
The DM9801 does not support this function. This bit is
permanently set to 0
Auto Configuration Ability:
The DM9801 does not support this function. This bit is
permanently set to 0
Link Status:
1=Valid link established
0=Link not established
The link status bit is implemented with a latching function, so that the
occurrence of a link failure condition causes the Link Status bit to be
cleared and remain cleared until it is read via the management
interface
Jabber Detect:
The DM9801 does not support this function. This bit is
permanently set to 0
Extended Capability:
The DM9801 does not support this function. This bit is
permanently set to 0

PHY ID Identifier Register #1 (PHYIDR1) - Register 2
The PHY Identifier Registers #1 and #2 work together in a single identifier of the DM9801. The Identifier consists of a
concatenation of the
Organizationally Unique Identifier
(OUI), a vendor's model number, and a model revision number.
DAVICOM Semiconductor's IEEE assigned OUI is 00606E.
