Bits R/W Register Name Description
[7:0]
syncstatus[7:0]
Records the synchronization status of the
corresponding bit. The RX sync status register has 1
bit per channel for a total of 4 bits per soft XAUI link;
soft XAUI uses bits 0–3. Reading the value of the
syncstatus register clears the bits.

0x085 [31:16] N/A Reserved N/A
[15:8] R
errdetect[7:0]
When set, indicates that a received 10-bit code group
has an 8B/10B code violation or disparity error. Use
errdetect with disperr to differentiate between a
code violation error, a disparity error, or both. There
are 2 bits per RX channel for a total of 8 bits per XAUI
link. Reading the value of the errdetect register
clears the bits.
From block: 8B/10B decoder
[7:0]
disperr[7:0]
Indicates that the received 10-bit code or data group
has a disparity error. When set, the corresponding
errdetect bits are also set. There are 2 bits per RX
channel for a total of 8 bits per XAUI link. Reading the
value of the errdetect register clears the bits.
From block: 8B/10B decoder
0x08a [0] RW
simulation_flag
Setting this bit to 1 shortens the duration of reset and
loss timer when simulating. Intel recommends that
you keep this bit set for simulation.
