13

POLOK²

Polarity OK: When this bit is high (default), the 10Base-T PHY receives valid (nonin-

 

 

verted) link pulses. If this bit goes low, it indicates that a sequence of seven consecutive

 

 

inverted link pulses has been detected.

12

TPENERGY

Twisted-pair energy detect: This bit only has meaning in AUI mode. When set to a 1, it

 

 

indicates that the PHY receives of impulses on the FRCVP/FRCVN pins. Energy is de-

 

 

tected in the form of link pulses, the sense of which is determined by the POLREV bit.

 

 

Note that if the POLREV bit is set incorrectly, link pulses are not seen and this bit is not

 

 

set.²

11±0

Reserved
