Integrated Programmable Interrupt Controller (IPIC)
The IPIC receives the following types of interrupts:
The interrupt controller provides the ability to mask each interrupt source. Any source that can be caused
by multiple events are also maskable.
When the IPIC receives an internal or external interrupt, its configuration register is checked to determine
if it should be routed off-chip (to the external PCI_INTA) or serviced as a normal external interrupt by the
processor core (through the int signal). As a third alternative, if the incoming interrupt has been configured
as a critical or system management interrupt, the IPIC completes the processing of the interrupt by
asserting cint or smi to the core. The assertion of the cint or smi signal to the core causes the interrupt to
be serviced as a critical or a system management interrupt, respectively.
8.2
The IPIC unit implements the following features:
8.3
The IPIC unit can operate in the core enable or core disable mode.
8.3.1
In core enable mode, all internal interrupts (including those from the PCI block) are routed to and from the
IPIC; the interrupts are sent to the PowerPC core. The DMA controller can optionally (depending on the
programming of the DMA registers) steer its interrupt to the PCI host through the PCI_INTA signal.
