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: DM9332, next page available
NP_ABLE = 0: DM9332, no next page
DM9332 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
0 = Normal operation
BYPASS ADPOK
Force signal detector (SD) active. This register is for debug only,
not release to customer
1=Forced SD is OK,
0=Normal operation
Reserved
Force to 0 in application
100BASE-TX Mode Control
1 = 100BASE-TX operation
0 = 100BASE-FX operation
Reserved
