The RTTP SECTION Accepted Trace Indirect Register is provided at RTTP r/w indirect address
80H to BFH.
ATRACE[7:0]:
The accepted tail trace message (ATRACE[7:0]) bits contain the persistent tail trace
message. When algorithm 2 is selected and PER5 is set to logic 1, the accepted message is
the same tail 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 tail 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 tail trace
byte received for 48 frames. When algorithm 3 is selected, the accepted byte is stored at
address 80h.
