This register is used to identify and acknowledge change of path signal label
interrupts for the tributaries TU #1 in TUG2 #1 to TUG2 #7. It is also used to
identify and acknowledge TU3 change of path signal label interrupts.
COPSL1I:
The COPSL1I bit identifies the source of change of path signal label
interrupts. In TU3 mode, the COPSL1I bit reports and acknowledges COPSL
interrupts of the TU3 stream. Out of TU3 mode, the COPSL1I bit reports and
acknowledges COPSL interrupt of TU #1 in TUG2 #1. Interrupts are
generated when the accepted PSL changes. The COPSL1I bit is set high
when a change of PSL event occurs and are cleared immediately following a
read of this register, which also acknowledges and clears the interrupt.
COPSL1I remains valid when interrupts are not enabled (COPSLE set low)
and may be polled to detect change of path signal label events.
COPSL2I-COPSL7I:
The COPSL2I to COPSL7I bits identify the source of change of path signal
label interrupts. In TU3 mode, these bits are unused and will return a logic 0
when read. Out of TU3 mode, COPSL2I to COPSL7I bits report and
acknowledge COPSL interrupt of TU #1 in TUG2 #2 to TUG2 #7, respectively.
Interrupts are generated when the accepted PSL changes. An COPSLxI bit is
