10 Mbits/s Serial Mode
1—10 Mbits/s serial mode
0—10 Mbits/s nibble mode
During 10Base-T operation, this bit deter-
mines whether the MII will be operating in
nibble mode or serial mode.
It is initialized to the logic level of SER-
SEL pin (pin 136).
1—Force 10 Mbits/s good link
0—Normal operation
Reserved.
1—Signal quality error test enabled
0—Default SQE is disabled
1—Low squelch level selected
0—Normal squelch level selected
1—Jabber function disabled
0—Normal operation
1—Detect mode switching in 10 Mbit
mode
0—Normal operation
When set to 1, the part will restart auto-
negotiation when it is in 10 Mbit mode
and detects 100 Mbit data reception.
