This register is used to identify and acknowledge trail trace identifier mismatch
interrupts for the tributaries TU #2 in TUG2 #1 to TUG2 #7.
TIM1I-TIM7I:
The TIM1I to TIM7I bits identify the source of trail trace identifier mismatch
interrupts. In TU3 mode, these bits are unused and will return a logic 0 when
read. When the corresponding TUG2 tributary group is configured for TU2
(VT6) mode, the associated TIMxI bit is unused and will return a logic 0 when
read. When operational, the TIM1I to TIM7I bits report and acknowledge TIM
interrupt of TU #2 in TUG2 #1 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
#2 in TUG2 #x) occurs and are cleared immediately following a read of this
register, which also acknowledges and clears the interrupt. TIMxI remains
valid when interrupts are not enabled (TIME set low) and may be polled to
detect trail trace identifier mismatch events.
