reserved (reads return 0)
unused (reads return 0)
Sticky bit which represents the state of the PME logic, regardless of the
state of the PMEEN bit.
reserved (reads return 0)
When set to 1, this bit enables the assertion of the PME function on the
PMEN pin. When 0, the PMEN pin is forced to be inactive. This value can
be loaded from the EEPROM.
unused (reads return 0)
This 2 bit field is used both to determine the current power state of
DP83820, and to set a new power state.
Reserved (reads return 0)
Returns 0 to indicate PCI clock not needed for PMEN.
Currently set to 010b.
Offset into PCI configuration space for the location of the next item in the
Capabilities Linked List. Returns 00h as no other capabilities are offered.
Always returns 01h for Power Management ID.
