The PCI interrupt register (PCIINT) is a 32-bit register that saves the error source when an error
occurs on the PCI bus as a result of the PCIC attempting to invoke a transfer on the PCI bus, or
when the PCIC is the PCI master or PCI target. This register can be read from both the PP bus and
PCI bus. Also, 1 can be written from either the PP bus or PCI bus to perform a write-clear in
which the detection bit is cleared to its initial value (0).
The PCIINT register is initialized to H'00000000 at a power-on reset or software reset.
