This set of registers reports the status and configures the operational modes of
TU #3 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) or VT3
mode, the associated register in this set has no effect.
TIUE:
The TIUE bit enables trail trace identifier unstable interrupts for tributary
TU #3 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 #3 in the corresponding TUG2.
TIME:
The TIME bit enables trail trace identifier mismatch interrupts for tributary
TU #3 in the corresponding TUG2. When TIME is set high, an interrupt is
generated upon detection of a mismatched identifier and upon return to a
