Description
Normal Status
Receive BIST Status
(Receive BIST = Enabled)
BIST Data Compare
. Character compared correctly.
Normal character received
.
The valid Data
character on the output bus meets all the
formatting requirements of Data characters
listed in
Table 15
.
Special code detected
. The valid special
character on the output bus meets all the
formatting requirements of Special Code
characters listed in
Table 16
, but is not the
presently selected framing character or a
decoder violation indication.
Receive Elasticity buffer underrun/overrun
error
.
The receive buffer was not able to
add/drop a K28.5 or framing character
Framing character detected
. This indicates
that a character matching the patterns
identified as a framing character (as selected
by FRAMCHARx) was detected. The decoded
value of this character is present in the
associated output bus.
Codeword violation
. The character on the
output bus is a C0.7. This indicates that the
received character cannot be decoded into any
valid character.
Loss of sync
.
This indicates a PLL Out of Lock
condition
001

BIST Command Compare
. Character compared
correctly.
010
2
BIST Last Good
. Last Character of BIST sequence
detected and valid.
011

100
4
BIST Last Bad
.
Last Character of BIST sequence
detected invalid.
101
1
BIST Start
. Receive BIST is enabled on this channel,
but character compares have not yet commenced.
This also indicates a PLL Out of Lock condition, and
Elasticity Buffer overflow/underflow conditions.
BIST Error
. While comparing characters, a mismatch
was found in one or more of the decoded character
bits.
BIST Wait
. The receiver is comparing characters. but
has not yet found the start of BIST character to enable
the LFSR.
110
6
Running disparity error
. The character on the
output bus is a C4.7, C1.7, or C2.7.
