PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE
TPP1I identifies tributary payload processor #1 as the source of a pending
interrupt. It is necessary to read the LOP Interrupt Status registers in
tributary processor #1 to determine the event causing the interrupt and to
clear the interrupt. Interrupts disabled at tributary payload processor #1 will
not be reported by the TPP1I bit.
TPP2I identifies tributary payload processor #2 as the source of a pending
interrupt. It is necessary to read the LOP Interrupt Status registers in
tributary processor #2 to determine the event causing the interrupt and to
clear the interrupt. Interrupts disabled at tributary payload processor #2 will
not be reported by the TPP2I bit.
TPP1I identifies tributary payload processor #3 as the source of a pending
interrupt. It is necessary to read the LOP Interrupt Status registers in
tributary processor #3 to determine the event causing the interrupt and to
clear the interrupt. Interrupts disabled at tributary payload processor #3 will
not be reported by the TPP3I bit.
