11 TEST_CNTR RW 0 = Normal operation.
1 = Increment bits[7:0] of register 0*17h counter for each
clock cycle.
0
10 BYPASS_PCS_TX RW 0 = Normal operation
1 = Bypass pcs transmit operation
0
9 BYPASS_PCS_RX RW 0 = Normal operation
1 = Bypass pcs receive operation
0
8 DISABLE_TRRR_GEN RW 0 = Normal operation
1 = Disable TRRR generation in pcs transmit
0
7 DISABLE_CARRIER_E
XTEND
RW 0 = Normal operation
1 = Disable carrier extension in pcs receive
0
6 AUTONEG_FAST_TIM
ERS
RW 0 = Normal operation
1 = Speed up timers during auto-negotiation for testing
0
5 FORCE_XMIT_DATA_
ON_TXSIDE
RW 0 = Normal operation
1 = Allow packets to be transmitted regardless of the
condition of the link or synchronization
0
4 DIS_REMOTE_FAULT
_SENSING
RW 0 = Automatically detect remote faults and send remote fault
status to link partner via auto-negotiation when fiber mode is
selected.
(SGMII does not support remote faults)
1 = Disable automatic sensing of remote faults, such as
auto-negotiation error
0
3 ENABLE_AUTONEG_
ERR_TIMER
RW 0 = Normal operation
1 = Enable auto-negotiation error timer. Error occurs when
timer expires in ability-detect, ack-detect, or idle-detect.
When the error occurs, config words of all zeros are sent
until an ability match occurs, then the autoneg-enable state
is entered.
0
2 FILTER_FORCE_LINK RW 0 = Normal operation
1 = Sync-status must be set for a solid 10ms before a valid
link will be established when auto-negotiation is disabled.
(This is useful in fiber applications where the user does not
have the signal detect pin connected to the fiber module and
auto-negotiation is turned off.)
1
1 DISABLE_FALSE_LIN
K
RW 0 = Normal operation
1 = Do not allow link to be established when auto-
negotiation is disabled and receiving auto-negotiation code
words. The link will only be established in this case after
idles are received. (This bit does not need to be set, if bit 0
below is set.)
1
0 ENABLE_PARALLEL_
DETECTION
RW 0 = Disable parallel detection
1 = Enable parallel detection. (This will turn auto-negotiation
on and off as needed to properly link up with the link partner.
The idles and auto-negotiation code words received from
the link partner are used to make this decision)
