This register is used to identify and acknowledge trail trace identifier mismatch
interrupts for the tributaries TU #4 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), VT3 or TU12 (VT2) 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 #4 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 #4 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.
