BIST Data Compare. Character compared correctly
BIST Command Compare. Character compared correctly
BIST Last Good. Last Character of BIST sequence detected and valid.
RESERVED for TEST
BIST Last Bad. Last Character of BIST sequence detected invalid.
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.
Normal Character Received. The valid data character with the correct running disparity received
Special Code Detected. Special code other than the selected framing character or decoder
violation received
Receive Elasticity Buffer underrun/overrun
error. The receive elasticity 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 was detected. The decoded value of this character is present on the associ-
ated 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.
PLL Out Of Lock Indication
Running Disparity Error. The character on the output bus is a C4.7, C1.7 or C2.7
