In TU3 mode (TU3 bit in VTPP Configuration register set high), this register
reports the status and configures operational modes of the TU3 mapped into a
TUG3 handled by the RTTB. Out of TU3 mode, this register reports the status
and configures the operational modes of TU #1 in TUG2 #1.
TIUE:
The TIUE bit enables trail trace identifier unstable interrupts for tributary
TU #1 in TUG2 #1 or TU3 When TIUE is set high, an interrupt is generated
upon detection of an unstable identifier and upon return to a stable identifier.
Interrupts due to TIU status change are masked when TIUE is set low.
TIUV:
The TIUV bit indicates the trail trace identifier unstable status of tributary
TU #1 in TUG2 #1 or TU3.
TIME:
The TIME bit enables trail trace identifier mismatch interrupts for tributary
TU #1 in TUG2 #1 or TU3. When TIME is set high, an interrupt is generated
upon detection of a mismatched identifier and upon return to a matched
