Reset values of the Duplex mode/status bit depends on the connection of the LED to the LEDB pin (see
Section 2.6 “LED Configuration” for additional details).
Unimplemented: Read as ‘0’
TXSTAT: PHY Transmit Status bit
1 = PHY is transmitting data
0 = PHY is not transmitting data
RXSTAT: PHY Receive Status bit
1 = PHY is receiving data
0 = PHY is not receiving data
COLSTAT: PHY Collision Status bit
1 = A collision is occuring
0 = A collision is not occuring
LSTAT: PHY Link Status bit (non-latching)
1 = Link is up
0 = Link is down
DPXSTAT: PHY Duplex Status bit
1 = PHY is configured for full-duplex operation (PHCON1<8> is set)
0 = PHY is configured for half-duplex operation (PHCON1<8> is clear)
Unimplemented: Read as ‘0’
PLRITY: Polarity Status bit
1 = The polarity of the signal on TPIN+/TPIN- is reversed
0 = The polarity of the signal on TPIN+/TPIN- is correct
Unimplemented: Read as ‘0’
