bit 7 bit 0

Legend: r = Reserved bit

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 (PHY is both transmitting and receiving while in Half-Duplex mode)

0 = A collision is not occuring

bit 10 LSTAT: PHY Collision Status bit

1 =Link is up

0 =Link is down

bit 9 Reserved: Ignore on read

bit 8-6 Unimplemented: Read as ‘0’

bit 5 Reserved: Ignore on read

bit 4-0 Unimplemented: Read as ‘0’
