It should be noted that the expected pattern while BIST[0:2]=011 is the same as
BIST[0:2]=101. But when coming out of the transmitter, the two bits with
*
in
BIST[0:2]=011 are different from BIST[0:2]=101. As a result, even when there is
no bit error, there will be bit errors intentionally introduced to verify the BIST
circuit is functional.
