Unimplemented: Read as ‘0’
PFDPX: PHY Full-Duplex Capable bit
1 = PHY is capable of operating at 10 Mbps in Full-Duplex mode (this bit is always set)
PHDPX: PHY Half-Duplex Capable bit
1 = PHY is capable of operating at 10 Mbps in Half-Duplex mode (this bit is always set)
Unimplemented: Read as ‘0’
LLSTAT: PHY Latching Link Status bit
1 = Link is up and has been up continously since PHSTAT1 was last read
0 = Link is down or was down for a period since PHSTAT1 was last read
JBSTAT: PHY Latching Jabber Status bit
1 = PHY has detected a transmission meeting the jabber criteria since PHSTAT1 was last read
0 = PHY has not detected any jabbering transmissions since PHSTAT1 was last read
Unimplemented: Read as ‘0’
