10.3.8.3
The processor who am I register (WHOAMI), 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 10-49
10.3.8.4
In systems based on processors that implement the Power Architecture technology, the interrupt
acknowledge function occurs as an explicit read operation to a memory-mapped interrupt acknowledge
register (IACK), shown in
vector corresponding to the highest priority pending interrupt. Reading IACK also has the following side
effects:
Reading this register when there is no pending interrupt returns the spurious vector value as described in
Section 10.3.1.8, “Spurious Vector Register (SVR).”
