PME Wake Status Register 3
This register is used to enable individual PME wake sources onto
the IO_PME# wake bus.
When the PME Wake Enable register bit for a wake source is
active (“1”), if the source asserts a wake event so that the
associated status bit is “1” and the PME_En bit is “1”, the source
will assert the IO_PME# signal.
When the PME Wake Enable register bit for a wake source is
inactive (“0”), the PME Wake Status register will indicate the state
of the wake source but will not assert the IO_PME# signal.

The PME Wake Enable register is not affected by Vcc POR, SOFT
RESET or PCI RESET.
PME Wake Enable Register 4
This register is used to enable individual PME wake sources onto

will assert the IO_PME# signal.
When the PME Wake Enable register bit for a wake source is
inactive (“0”), the PME Wake Status register will indicate the state
of the wake source but will not assert the IO_PME# signal.
