bit 7 bit 0

Legend:

R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’

-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown

bit 15-14 Unimplemented: Read as ‘0’

bit 13 TXSTAT: PHY Transmit Status bit

1 = PHY is transmitting data

0 = PHY is not transmitting data

bit 12 RXSTAT: PHY Receive Status bit

1 = PHY is receiving data

0 = PHY is not receiving data

bit 11 COLSTAT: PHY Collision Status bit

1 = A collision is occuring

0 = A collision is not occuring

bit 10 LSTAT: PHY Link Status bit (non-latching)

1 =Link is up

0 =Link is down

bit 9 DPXSTAT: PHY Duplex Status bit

(1)

1 = PHY is configured for full-duplex operation (PHCON1<8> is set)

0 = PHY is configured for half-duplex operation (PHCON1<8> is clear)

bit 8-6 Unimplemented: Read as ‘0’

bit 5 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

bit 4-0 Unimplemented: Read as ‘0’

Note 1: 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).
