STE100P 
10/31
6 MFPS MF Preamble Suppression 
1 =Accepts management frames with pre-amble suppressed. 
0 = Will not accept management frames with preamble 
suppressed. The value of this bit is controlled by bit 1 of PR20. 
Its default of 1 indicates that the SFEPHY1 accepts 
management frame without preamble. A minimum of 32 
preamble bits are required following power-on or hardware 
reset. One IDLE bit is required between any two management 
transactions as per IEEE 802.3u specification.
1RO
5 ANC Auto-Negotiation Completed. 
0: Auto-Negotiation process is not completed.
1: Auto-Negotiation process is completed. (PR0, Bit 12 is set)
0RO
4 RF Result of remote fault detection. 
0: No remote fault condition detected.
1: Remote fault condition detected. 
This bit is set when the Link Partner transmits a remote fault 
condition (PR5 bit 13 = 1).
0RO/LH*
3 AN Auto-Negotiation ability. 
Always 1, since STE100P has the Auto-Negotiation ability.
1RO
2 LINK Link status. 
0: a failure link condition occurred. (Latched until read)
1: a valid link is established. 
0 RO/LL*
1 JAB Jabber detection. 
1: jabber condition is detected (10Base-T only). 
0RO/LH*
0 EXT Extended register supporting. 
Always 1, since STE100P supports extended register
1RO
LL* = Latching Low and clear by read. LH* = Latching High and clear by read.

9~4 MODEL Model number of STE100P. 
Six bits manufacture’s model number. 
000001b RO
3~0 REV Revision number of STE100P. 
Four bits manufacture’s revision number. 
0001b RO
PR4- ANA, Auto-Negotiation Advertisement
15 NXTPG Next Page ability. 
Always 0: since STE100P does not provide next page ability.
