This register, together with the SPTX Master Interrupt Status #2 register, allow
the source of an active interrupt to be identified down to the block level. Further
register accesses to the block in question are required in order to determine
each specific cause of an active interrupt and to acknowledge each interrupt
source.
RTALnI:
The RTALnI bits are high when an interrupt request is active from the
corresponding RTAL block.
RPOPnI:
The RPOPnI bits are high when an interrupt request is active from the
corresponding RPOP block.
DPAIS:
The DROP bus alarm indiction signal (DPAIS) bit is set high when path AIS is
inserted in the DROP bus. In STS-3 mode, DPAIS is set high when AIS is
inserted in any of the three STS-1 streams
These register bits are not cleared on read.
