00 = Lane 0 (Default 2’b00)
01 = Lane 1
10 = Lane 2
11 = Lane 3
C.11:10 LAS_CH_SYNC_HYS_SEL[1:0]
Lane alignment slave Channel synchronization hysteresis selection
RW
00 = The channel synchronization, when in the synchronization state, performs
the Ethernet standard specified hysteresis to return to the LOS state
(Default 2’b00)
01 = A single 8b/10b invalid decode error or disparity error causes the channel
synchronization state machine to immediately transition from sync to LOS
10 = Two adjacent 8b/10b invalid decode errors or disparity errors cause the
channel synchronization state machine to immediately transition from sync
to LOS
11 = Three adjacent 8b/10b invalid decode errors or disparity errors cause the
channel synchronization state machine to immediately transition from sync
to LOS

LS_DECODE_ERR_MASK
0 = LS side decode errors of enabled lanes are used to generate link status if
error rate exceeds threshold. Valid only when hardware BER function is
enabled by setting A.13 to 1'b1.
1 = LS side decode errors of any lane are not used to generate link status
(Default 1’b1)
