Description
Reserved:
Write as 0, ignore on read
Local Device Parallel Detection Fault:
PDF=1: A fault detected via parallel detection function.
PDF=0: No fault detected via parallel detection function
DM9801 does not support this function, so this bit is always 0.
Link Partner Next Page Able:
LP_NP_ABLE=1: Link partner, next page available
LP_NP_ABLE=0: Link partner, no next page
DM9801 does not support this function, so this bit is always 0.
Local Device Next Page Able:
NP_ABLE=1: DM9801, next page available
NP_ABLE=0: DM9801, no next page
DM9801 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.
DM9801 does not support this function, so this bit is always 0.
Link Partner Auto-negotiation Able:
LP_AN_ABLE=1 indicates that the link partner supports Auto-
negotiation.
DM9801 does not support this function, so this bit is always 0.

Description
Ignore Remote Commands:
1=Remote commands are ignored
0=Remote commands will be accepted from any node in the
network. The value of the CMDENA pin is latched into this bit at
power-up/reset.
Average Peak Rule:
1= Average peak with measured noise instead of noise + 25%
0= Normal operation
Enable Short CD:
1= Enable short CD noise rule
Do not count bad SYNC if CD is longer than 160uS
0= Normal operation
Disable Increment of Noise:
1= Disable 25% increase of noise slice when in a packet
0= Normal operation
Command Low Power:
1= Transmit power is set to low
0= Normal operation
Remote commands will be issued if this bit is set
Command High Power:
1= Transmit power is set to high
0= Normal operation
Remote commands will be issued if this bit is set
