9'h33
Reserved
9'h34 RX_PRBS_DONE RO [NUM_LANES–1:0] – Indicates whether enough bits have
been received on the corresponding RX lane for one
complete pass through the PRBS polynomial.
If you turn off Include diagnostic features, this register is
not available.
9'h35 RX_PRBS_ERR RO [NUM_LANES–1:0] – Sticky flag that indicates whether a
PRBS error has occurred on the corresponding RX lane
after
RX_PRBS_DONE
has attained the value of 1.
If you turn off Include diagnostic features, this register is
not available.
9'h36 RX_PRBS_COUNT RO [7:0] – This eight-bit counter holds the number of words
that had PRBS errors across all lanes. Saturates at the value
of 0xFF.
If you turn off Include diagnostic features, this register is
not available.
9'h37 RX_PRBS_CTRL RW Bit [0] – If you set this bit to the value of 1, the IP core
clears the
RX_PRBS_DONE
,
RX_PRBS_ERR
, and
RX_PRBS_
COUNT
registers. Reset this bit to the value of 0 to capture
new PRBS status.
If you turn off Include diagnostic features, this register is
not available.
9'h38 CRC32_ERR_INJECT RW [NUM_LANES–1:0] - When a bit has the value of 1, the IP
core injects CRC32 errors on the corresponding TX lane.
When it has the value of 0, the IP core does not inject errors
on the TX lane. You must maintain each bit at the value of 1
for the duration of a Meta Frame, at least, to ensure that the
IP core transmits at least one CRC32 error.
If you turn off Include diagnostic features, this register is
not available.
