INTERFACES
interrupt and to clear the interrupt. Interrupts disabled at tributary path
overhead processor #3 will not be reported by the RTOP3I bit.
RTTB1I:
RTTB1I identifies tributary trace buffer #1 as the source of a pending
interrupt. It is necessary to read the various interrupt status registers in
tributary trace buffer #1 to determine the event causing the interrupt and to
clear the interrupt. Interrupts disabled at tributary trace buffer #1 will not be
reported by the RTTB1I bit.
RTTB2I:
RTTB2I identifies tributary trace buffer #2 as the source of a pending
interrupt. It is necessary to read the various interrupt status registers in
tributary trace buffer #2 to determine the event causing the interrupt and to
clear the interrupt. Interrupts disabled at tributary trace buffer #2 will not be
reported by the RTTB2I bit.
RTTB3I:
RTTB1I identifies tributary trace buffer #3 as the source of a pending
interrupt. It is necessary to read the various interrupt status registers in
tributary trace buffer #3 to determine the event causing the interrupt and to
clear the interrupt. Interrupts disabled at tributary trace buffer #3 will not be
reported by the RTTB3I bit.
