Reserved:
Write as 0, ignore on read
Flow control support:
1 = Controller chip supports flow control ability by link partner
0 = Controller chip doesn’t support flow control ability by link
partner
100BASE-T4 support:
1 = 100BASE-T4 is supported by the link partner
0 = 100BASE-T4 is not supported by the link partner
100BASE-TX full duplex support:
1 = 100BASE-TX full duplex is supported by the link partner
0 = 100BASE-TX full duplex is not supported by the link partner
100BASE-TX support:
1 = 100BASE-TX half duplex is supported by the link partner
0 = 100BASE-TX half duplex is not supported by the link partner
10BASE-T full duplex support:
1 = 10BASE-T full duplex is supported by the link partner
0 = 10BASE-T full duplex is not supported by the link partner
10BASE-T support:
1 = 10BASE-T half duplex is supported by the link partner
0 = 10BASE-T half duplex is not supported by the link partner
Protocol selection bits:
Link partner’s binary encoded protocol selector
Reserved:
Write as 0, ignore on read
Local device parallel detection fault:
PDF = 1 : A fault detected via parallel detection function.
PDF = 0 : No fault detected via parallel detection function
Link partner next page able:
LP_NP_ABLE = 1 : Link partner, next page available
LP_NP_ABLE = 0 : Link partner, no next page
Local device next page able:
NP_ABLE = 1 : next page available
NP_ABLE = 0 : no next page
New page received:
A new link code word page received. This bit will be automatically
cleared when the register (register 6) is read by management.
Link partner auto-negotiation able:
A “1” in this bit indicates that the link partner supports
Auto-negotiation.
Bypass 4B5B encoding and 5B4B decoding :
1 = 4B5B encoder and 5B4B decoder function bypassed
0 = Normal 4B5B and 5B4B operation
Bypass scrambler/descrambler function :
USB2.0 to Fast Ethernet Controller
