RX_LANE_SYNC 0 = Receiver lane not in sync
1 = Receiver lane in sync
RO
0

LP_RX_TRAINED 0 = Link partner receiver not trained
1 = Link partner receiver trained
This bit represents the value state of the local far_rcvr_trained
signal defined in Part 6 of the RapidIO Specification (Rev. 2.1).

RX_LANE_RDY
Receiver Lane Ready
0 = Not ready
1 = Ready

ERR_8B10B
A saturating count of 8b/10b decoding errors that have been
detected for this lane since the field was last read. The field is
reset to 0b0000 when the register is read.
RR
0b0000
25
RX_SYNC_CHG
Indicates whether the lane_sync signal for this lane has changed
state since the bit was last read. The bit is reset to 0 when the
register is read.
0 = The state of lane_sync did not change since the bit was last
read.
1 = The state of lane_sync changed since the bit was last read.
RR
0
26
RX_TRAINED_CHG
Indicates whether the lane_ready signal for this lane has changed
state since the bit was last read. The bit is reset to 0 when the
register is read.
0 = The state of lane_ready did not change since the bit was last
read.
1 = The state of lane_ready changed since the bit was last read.

implemented by the device
0b000 = None of the Lane Status CSRs 2:7 are implemented
0b001 = Lane Status CSR 2 is implemented
0b010 = Lane status CSRs 2:3 are implemented
0b011 = Lane status CSRs 2:4 are implemented
0b100 = Lane status CSRs 2:5 are implemented
0b101 = Lane status CSRs 2:6 are implemented
0b110 = Lane status CSRs 2:7 are implemented
0b111 = Reserved
