Description
This is a self-clearing bit.
Counts the number of non-collision
packets with receive errors after the last
read. The PHY increments these bits
each time the Carrier Integrity Monitor
(CIM) enters the link unstable state. The
counter stops counting at 0FFh. This
register is cleared only when read or
upon a hardware or software reset.
Description
This is a sticky bit.
1 = Bypass link integrity test.
0 = Enable link integrity test.
This is a sticky bit.
1 = Disable jabber detect.
This is a sticky bit.
1 = Disable 10BASE-T echo.
1 = Disable SQE transmit.
This is a sticky bit.
00 = Normal squelch.
01 = Low squelch.
10 = High squelch.
11 = Reserved.
This bit is self-clearing.
1 = EOF error detected.
This bit is self-clearing.
1 = 10BASE-T link disconnect detected.
1 = 10BASE-T link active.
