RTIMV:
The receive trace identifier mismatch value status bit (RTIMV) is set high
when the accepted message differs from the expected message. RTIMV is
set low when the accepted message is equal to the expected message. A
mismatch is not declared if the accepted trail trace message string is all-
zeros.
RTIMI:
The receive trace identifier mismatch indication status bit (RTIMI) is set high
when match/mismatch status of the trace identifier framer changes state.
This bit (and the interrupt) is cleared when this register is read.
RTIUV:
The receive trace identifier unstable value status bit (RTIUV) is set high when
8 messages that differ from its immediate predecessor are received. RTIUV
is set low and the unstable message count is reset when 3 or 5 (depending
on PER5 control bit) consecutive identical messages are received.
RTIUI:
The receive trace identifier unstable indication status bit (RTIUV) is set high
when the stable/unstable status of the trace identifier framer changes state.
This bit (and the interrupt) is cleared when this register is read.
