Programmable Interrupt Controller (PIC)
9.3.8.3
The processor core WHOAMIn register, shown in
determine its physical connection to the PIC. The value returned when reading this register may be used
to determine the value for the destination masks used for dispatching interrupts.
Table 9-47
9.3.8.4
In systems based on processors built on Power Architecture™ technology, the interrupt acknowledge
function occurs as an explicit read operation to a memory-mapped interrupt acknowledge register (IACK),
shown in
interrupt vector corresponding to the highest priority pending interrupt. Reading IACK also has the
following side effects:
Reading IACK when no interrupt is pending returns the spurious vector value, as described in
Section 9.3.1.8, “Spurious Vector Register (SVR).”
