This register is used to identify and acknowledge trail trace identifier mismatch
interrupts for the tributaries TU #1 in TUG2 #1 to TUG2 #7. It is also used to
identify and acknowledge TU3 trail trace identifier mismatch interrupts.
TIM1I:
The TIM1I bit identifies the source of trail trace identifier mismatch interrupts.
In TU3 mode, The TIM1I bit reports and acknowledges TIM interrupt of the
TU3 trail trace identifier. Out of TU3 mode, TIM1I bit reports and
acknowledges TIM interrupt of TU #1 in TUG2 #1. Interrupts are generated
upon change of identifier mismatch state. The TIM1I bit is set high when a
trail trace identifier mismatch event and is cleared immediately following a
read of this register, which also acknowledges and clears the interrupt. the
TIM1I bit remains valid when interrupts are not enabled (TIME set low) and
may be polled to detect trail trace identifier mismatch events.
TIM2I-TIM7I:
The TIM2I to TIM7I bits identify the source of trail trace identifier mismatch
interrupts. TIM2I to TIM7I bits report and acknowledge TIM interrupt of TU #1
in TUG2 #2 to TUG2 #7, respectively. Interrupts are generated upon change
of identifier mismatch state. An TIMxI bit is set high when a trail trace identifier
mismatch event on the corresponding tributary (TU #1 in TUG2 #x) occurs
