This set of registers reports the status and configures the operational modes of
TU #2 in TUG2 #1 to TUG2 #7. These registers have no effect in TU3 mode.
When the corresponding TUG2 tributary group is configured to TU2 (VT6) mode,
the associated register in this set has no effect.
TIUE:
The TIUE bit enables trail trace identifier unstable interrupts for tributary
TU #2 in the corresponding TUG2. 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 #2 in the corresponding TUG2.
TIME:
The TIME bit enables trail trace identifier mismatch interrupts for tributary
TU #2 in the corresponding TUG2. When TIME is set high, an interrupt is
generated upon detection of a mismatched identifier and upon return to a
