PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE
The OOF1I bit indicates a change of status in the H4 byte framer. Interrupts
are generated when the H4 framer in tributary payload processor #1 goes out
of frame and when it re-acquires frame. The OOF1I bit is set high when an
out of frame event occurs and is cleared immediately following a read of this
register, which also acknowledges and clears the interrupt. The OOFI bit
remains valid when interrupts are not enabled (OOF1E set low) and may be
polled to detect out of frame events.
The OOF2I bit indicates a change of status in the H4 byte framer. Interrupts
are generated when the H4 framer in tributary payload processor #2 goes out
of frame and when it re-acquires frame. The OOF2I bit is set high when an
out of frame event occurs and is cleared immediately following a read of this
register, which also acknowledges and clears the interrupt. The OOF2I bit
remains valid when interrupts are not enabled (OOF2E set low) and may be
polled to detect out of frame events.
The OOF3I bit indicates a change of status in the H4 byte framer. Interrupts
are generated when the H4 framer in tributary payload processor #2 goes out
