Capability Identifier
Bits 31-16 are Power Management Capability register. It is loaded from EEPROM at power on if EEPROM is not empty, else the
default value is used.
Bit 31-27 PME-Support
Indicate states which can assert PME# signal:
XXXX1b - PME# can be asserted from D0
XXX1Xb - PME# can be asserted from D1
XX1XXb - PME# can be asserted from D2
X1XXXb - PME# can be asserted from D3_hot
1XXXXb - PME# can be asserted from D3_cold
Default is 11111b.
