RTIUI:
When TIMODE is high, RTIUV is set low during the stable state which is declared after
having received the same trace byte for 48 consecutive SONET/SDH frames. The stable
byte is declared the accepted byte. RTIUV is set high when mismatches between the
accepted byte and the received byte have been detected for three consecutive 16 byte
windows. The 16 byte windows do not overlap and start immediately after the 48
persistent byte.
The RTIUI bit is a logic one when stable/unstable status of the trace identifier framer
changes state. When RTIUV changes value, RTIUI is set high. This bit is cleared when this
register is read.
