Table 2-19. XS_CONTROL_1
1 = XGXS reset (including all registers)
0 = Normal operation (Default)
1 = Enable loop back mode.
If the device is configured as PHY XS (PRTAD(0) = 0), then
XAUI_DATA_LOOPBACK will be performed (Same as SLOOP).
If the device is configured as DTE XS (PRTAD(0) = 1), then
XGMII_DATA_LOOPBACK will be performed (Same as PLOOP)
0 = Disable loop back mode (Default)
This bit always reads 1 indicating operation at 10 Gbps and above.
1 = Low power mode
0 = Normal operation (Default)
In low power mode all the internal clocks and datapaths are placed in shut
down mode. After de-assertion of this bit, datapath reset (4/5.32800.15)
needs to be performed to achieve proper datapath function. Serdes PLL's
can be shut down by de-asserting bits 4/5.36864.12 and 4/5.36864.4. Jitter
cleaner PLL can be shut down by de-asserting 4/5.37127.15
This bit always reads 1 indicating operation at 10Gbps and above.
These bits always read 0 indicating operation at 10Gbps.
Table 2-20. XS_STATUS_1
1 = Fault condition detected
(either on TX or RX side. This bit is OR ed version of 4/5.8.10 and 4/5.8.11)
0 = No fault condition detected
1 = XS Transmit link is up.
0 = XS Transmit links is down.
(This bit is latched low version of 4/5.24.12)
This bit always reads 1 indicating support for low power mode
