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: DM9008A, next page available
NP_ABLE = 0: DM9008A, no next page
DM9008A 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
