The accepted trail trace message (ATRACE[7:0]) bits contain the persistent trail trace
message. When algorithm 1 is selected, the accepted trail trace will not be updated. When
algorithm 2 is selected and PER5 is set to logic 1, the accepted message is the same trail
trace message received for 5 consecutive multi-frames. When algorithm 2 is selected and
PER5 is set to logic 0, the accepted message is the same trail trace message received for 3
consecutive multi-frames. When algorithm 2 is selected and LENGTH16 is set to logic 1,
the accepted message is stored between address 80h and 8Fh. When algorithm 2 is selected
and LENGTH16 is set to logic 0, the accepted message is stored between address 80h and
BFh. When algorithm 3 is selected, the accepted byte is the same trail trace byte received
for 48 frames. When algorithm 3 is selected, the accepted byte is stored at address 80h.
