10/100Mbps Ethernet Fiber/Twisted Pair Single Chip Media Converter
Collision Test
1 = Collision test enabled. When set, this bit will cause the COL
signal to be asserted in response to the assertion of TX_EN in
internal MII interface.
0 = Normal operation
Reserved
Read as 0, ignore on write
100BASE-T4 Capable
1 = DM9332 is able to perform in 100BASE-T4 mode
0 = DM9332 is not able to perform in 100BASE-T4 mode
100BASE-TX Full Duplex Capable
1 = DM9332 is able to perform 100BASE-TX in full duplex mode
0 = DM9332 is not able to perform 100BASE-TX in full duplex mode
100BASE-TX Half Duplex Capable
1 = DM9332 is able to perform 100BASE-TX in half duplex mode
0 = DM9332 is not able to perform 100BASE-TX in half duplex
mode
10BASE-T Full Duplex Capable
1 = DM9332 is able to perform 10BASE-T in full duplex mode
0 = DM9332 is not able to perform 10BASE-TX in full duplex mode
10BASE-T Half Duplex Capable
1 = DM9332 is able to perform 10BASE-T in half duplex mode
0 = DM9332 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
Remote Fault
1 = Remote fault condition detected (cleared on read or by a chip
reset). Fault criteria and detection method is DM9332
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 = DM9332 is able to perform auto-negotiation
0 = DM9332 is not able to perform auto-negotiation
Link Status
1 = Valid link is established (for either 10Mbps or 100Mbps
operation)
0 = Link is not established
