PME Enable Register 6
This register is used to enable individual PME sources onto the nIO_PME
signal.
When the PME Enable register bit for a PME source is active (“1”), if the
source asserts a PME event and the PME_EN bit is “1”, the source will
assert the nIO_PME signal.
When the PME Enable register bit for a PME source is inactive (“0”), the
PME Status register will indicate the state of the PME source but will not
assert the nIO_PME signal.

PCI RESET.

Bit[7:0] Reserved
PME Wake Status Register 7
This register indicates the state of the individual PME wake sources,
independent of the individual source enables or the PME_EN bit.
If the wake source has asserted a wake event, the associated PME Wake
Status bit will be a “1”. If enabled, any set bit in this register asserts the
nIO_PME pin.

The PME Wake Status register is not affected by Vcc POR, SOFT RESET
or PCI RESET.
Writing a “1” to Bit[7:0] will clear it. Writing a “0” to any bit in PME Wake
Status Register has no effect.
