NPJI[1]:
The negative pointer justification interrupt status (NPJI[1]) bit indicates a negative pointer
adjustment in the STS-48c/STM-4-4c stream. NPJI[1] is set to logic 1 to indicate a negative
pointer justification event in the outgoing data stream. This interrupt status bit is independent
of the interrupt enable bit. NPJI[1] is cleared to logic 0 when this register is read.
