100BASE-T4 Capable
The DM9008A is not support 100BASE-T4 mode.
100BASE-TX Full Duplex Capable
The DM9008A is not support 100BASE-TX full duplex mode.
100BASE-TX Half Duplex Capable
The DM9008A is not support 100BASE-TX half duplex mode
10BASE-T Full Duplex Capable
1 = DM9008A is able to perform 10BASE-T in full duplex
mode
0 = DM9008A is not able to perform 10BASE-TX in full
10BASE-T Half Duplex Capable
1 = DM9008A is able to perform 10BASE-T in half duplex
mode
0 = DM9008A is not able to perform 10BASE-T in half
duplex mode
Reserved
Read as 0, ignore on write
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
1 = Auto-negotiation process completed
0 = Auto-negotiation process not completed
1 = Remote fault condition detected (cleared on read or by a
chip reset). Fault criteria and detection method is DM9008A
implementation specific. This bit will set after the RF bit in
the ANLPAR (bit 13, register address 05) is set
0 = No remote fault condition detected
Auto Configuration Ability
1 = DM9008A is able to perform auto-negotiation
0 = DM9008A is not able to perform auto-negotiation
duplex mode
