Programmable Interrupt Controller
10.1.5.1
When an interrupt request is delivered to the PIC, the corresponding interrupt destination register is checked
to determine where the request should be routed, as follows:

Internal Interrupt

Number
Message registers—From inside the PIC. Triggered on register write, cleared on read. Used for
inter-process communication.
Shared message signaled interrupt registers—From within the PIC. Triggered on register write;
cleared on read.
If xIDRn[EP] = 1 (and all other destination bits are zero), the interrupt is routed off-chip to the
external signal. Or if the PCI Express controller is in EP mode and automatically generates a PCI
Express MSI transaction. See
If xIDR[CI] is set (and all other destination bits are zero), the interrupt is routed to cint.
If xIDRn[P0] is set (and all other destination bits are zero) the interrupt is routed to int0. Setting
xIDRn[P1] likewise routs the interrupt to int1 In this case, the interrupt is latched by the interrupt
pending register (IPR) and the interrupt flow is as described in
Control.”
