RTTP Operation
The RTTP monitors a one-byte, 16-byte or 64-byte trail trace message. To monitor a one-byte
message, ALGO register bits must be set to 11 (algorithm 3). The trail trace byte is captured at
address offset 40H. To monitor a 16-byte message, ALGO register bits must be set to 01/10
(algorithm 1/2) and LENGTH16 register bit must be set to logic one. The trail trace message is
captured between address offset 40H and offset 4FH. To monitor a 64-byte message, ALGO
register bits must be set to 01/10 (algorithm 1/2) and LENGTH16 register bit must be set to
logic zero. The trail trace message is captured between address offset 40H and offset 7FH.
When SYNC_CRLF is low, the synchronization is based on the MSB of the trail trace byte.
Only one of the bytes has its MSB set high. The byte with its MSB set high is the first byte of
the message. When SYNC_CRLF is high, the synchronization is based on the CR/LF (CR =
0Dh, LF = 0Ah) characters of the trail trace message. The byte following the CR/LF bytes is the
first byte of the message.
Set FSBEN to logic one and FSB[7:0] to the desired value for the corresponding path of the
VC-3 in the THPP_R.
Set UNEQ to logic one and UNEQV to the desired value for path 1 of the master and slaves
THPP_Rs.
Set UNEQ to logic one and UNEQV to the desired value for path 1 of the THPP_R.
Set UNEQ to logic one and UNEQV to the desired value for the STS-3C/VC-4
corresponding path: 1, 2, 3 or 4.
Set UNEQ to logic one and UNEQV to the desired value for the corresponding path of the
VC-3 in the THPP_R.
