Programmable Interrupt Controller (PIC)
Table 9-31
9.3.5.3
The message status register (MSR) shown in
status bit is set when the corresponding messaging interrupt is active. Writing a 1 to a status bit clears the
corresponding message interrupt and the status bit.
Table 9-32
9.3.6
This section contains description the shared message signaled interrupt registers (MSIRs). The shared
message signaled interrupt structure allows programs to interrupt each other by simply writing to these
shared memory-mapped registers in the PIC. Each of the eight MSIRs can be thought of as collecting
interrupts from 32 different memory-mapped writes that can cause interrupts.
