Default
0, RO
Description
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: DM9161A, next page available
NP_ABLE = 0: DM9161A, no next page
DM9161A 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

8.8 DAVICOM Specified Configuration Register (DSCR) - 16
Bit
Bit Name
16.15
BP_4B5B
Default
0,RW
Description
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
(Pin#38),RW Repeater/Node Mode
The value of the Repeater/Node pin (38) is latched into this bit at
power-up/reset
1 = Repeater mode
0 = Node mode
1, RW
100BASE-TX Mode Control
1 = 100BASE-TX operation
1, RO
Reserved
