PARDETFLT

Parallel detection fault: For multi-technology PHYs, this bit indicates multiple valid links.

 

 

This PHY only supports a single technology (10Base-T) and so this bit should be

 

 

ignored.

3

LPNPABLE

Link partner next page able: When this bit is set to 1, the link partner indicates that it

 

 

implements autonegotiation next page abilities.

2

0

Next page able: ThunderLAN does not support next page transmission or reception.

PAGERX

Page received: This bit is set after three identical and consecutive link code words have

 

 

been received from the link partner and the link partner has indicated that it has received

 

 

three identical and consecutive link code words from ThunderLAN. This bit is cleared

 

 

when read.

0

 

 

 

LPANABLE

Link-Partner Autonegotiation Able: When this bit is set to a one, the PHY is receiving

 

 

 

autonegotiation fast link pulse bursts from the link partner. This bit is reset to zero if the

 

 

 

Link-Partner is not autonegotiation able.
