This bit indicates that another PME is pending when the PME
Status bit is set. When the PME Status bit is cleared by software,
the PME is delivered by hardware by setting the PME Status bit
again and updating the Requestor ID appropriately. The PME
pending bit is cleared by hardware if no more PMEs are pending.

PME Status (PMES)
This bit indicates that PME was asserted by the requestor ID
This bit indicates that PME was asserted by the requestor ID
indicated in the PME Requestor ID field. Subsequent PMEs are
kept pending until the status register is cleared by writing a 1 to
this field.
