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 15-5
Reserved: Write as ‘0’, ignore on read
bit 4
PLRITY: TPIN+/- Polarity Status bit (applies to 10Base-T only)
1 = Wiring on the TPIN+/- pins is reversed polarity. PHY internally swaps the TPIN+/- signals to get the
correct polarity.
0 = Wiring on the TPIN+/- is correct polarity
bit 3-0
Reserved: Ignore on read
