Description
Low power controls:
00 = full receive path active. No transmit.
01 = Deep sleep (all off including VREF & OSC)
10 = Sleep (generate MII interrupt on activity)
11 = auto shut down, auto wake on activity
1 = MINT output active high
0 = MINT output active low
1 = disable 10Base-T autopolarity correction
1 = disable SQE in 10Base-T half duplex mode
0 = in case of jabber the 10Base-T will cut the
transmitted frame (normal operation)
1 = Jabber function disable
1 = enable MII loopback in 10Base-T half duplex mode
Force receive regardless of link
Force transmit regardless of link
CRS behavior in full duplex mode:-
0 = CRS is active for transmit only
1= CRS active for receive or transmit
1 = MDIO data accepted without preamble
0 = normal operation
1 = bypass the aligner function
0 = normal operation
1 = bypass the 4B5B encoder function
0 = normal operation
1 = bypass the scrambler function
0 = disable disconnection events
1 = enable disconnect on false carrier detection
Set repeater mode (affects CRS generation)
