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

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: DM9302, next page available
NP_ABLE = 0: DM9302, no next page
DM9302 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
