Industrial-temperature Single Chip Ethernet Controller with General Processor Interface
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
Link partner’s binary encoded protocol selector
Reserved
Read as 0, ignore on write
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: DM9010BI, next page available
NP_ABLE = 0: DM9010BI, no next page
DM9010BI does not support this function, so this bit is always 0
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
1 = Scrambler and descrambler function bypassed
0 = Normal scrambler and descrambler operation
Bypass Symbol Alignment Function
1 = Receive functions (descrambler, symbol alignment and symbol
decoding functions) bypassed. Transmit functions (symbol encoder
and scrambler) bypassed
