PMCInt0
If Power Management is enabled this bit functions as PMC0 interrupt,
otherwise it functions as one of the CPUInt bits.
PMCInt: Asserts when power state bits in PMCSR0 register
are updated from PCI.
CPUInt: Set by the CPU by writing ‘0’ to generate an inter-
rupt on the PCI bus. Cleared when the PCI writes ‘0’.
0
25:22
CPUInt
These bits are set by the CPU by writing ‘0’ to generate an interrupt on
the PCI bus. They are cleared when the PCI writes ‘0’. This requires
that Interrupt1* is used as a PCI interrupt signal.
0
29:26
PCIInt
These bits are set by the PCI by writing ‘0’ to generate an interrupt on
the CPU. They are cleared when the CPU writes ‘0’.

Int0*Sum
Interrupt Summary
Logical OR of all interrupt bits in the main and high Cause registers
masked by Interrupt0* mask registers.
This bit is read-only.
0
31
Int1*Sum
Interrupt Summary
Logical OR of all interrupt bits in the main and high Cause registers
masked by Interrupt1* mask registers.
This bit is read-only.
