This register is used to identify and acknowledge path signal label mismatch
interrupts for the tributaries TU #3 in TUG2 #1 TO TUG2 #7.
PSLM1I-PSLM7I:
The PSLM1I to PSLM7I bits identify the source of path signal label 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) or VT3 mode, the associated PSLMxI bit is unused and will return a
logic 0 when read. When operational, the PSLM1I to PSLM7I bits report and
acknowledge PSLM interrupt of TU #3 in TUG2 #1 to TUG2 #7, respectively.
Interrupts are generated when the accepted PSL becomes matched to the
expected PSL or becomes mismatched to the expected PSL. An PSLMxI bit is
set high when a change of PSL matched state on the associated tributary (TU
#3 in TUG2 #x) occurs and are cleared immediately following a read of this
register, which also acknowledges and clears the interrupt. PSLMxI remains
valid when interrupts are not enabled (PSLME set low) and may be polled to
detect path signal label match/mismatch events.
