ALGO[1:0]:
The tail trace algorithm select (ALGO[1:0]) bits select the algorithm used to process the tail
trace message.

When ALGO[1:0] is set to logic 00b, the tail trace algorithms are disable. The corresponding
TIUV, TIMV register bits and the corresponding TIU, TIM output signal time slots are set to
logic 0.
LENGTH16:
The message length (LENGTH16) bit selects the length of the tail trace message use by
algorithm 1 and algorithm 2. When LENGTH16 is set to logic 1, the length of the tail trace
message is 16 byte. When LENGTH16 is set to logic 0, the length of the tail trace message
is 64 byte.
