PME_Support (PMESUPPORT):
This 5-bit field indicates the power states in which the
function may assert PME#. A value of 0b for any bit indicates that the function is not
capable of asserting the PME# signal while in that power state.
•
•
bit(11) X XXX1b - PME# can be asserted from D0.
•
bit(12) X XX1Xb - PME# can be asserted from D1. Bridge does not support this
state.
•
bit(13) X X1XXb - PME# can be asserted from D2. Bridge does not support this
state.
•
bit(14) X 1XXXb - PME# can be asserted from D3hot.
•
bit(15) 1 XXXXb - PME# can be asserted from D3cold. Bridge does not support this
state.
This field is taken from the strap strap_pme_support.

PME Status (PMESTATUS):
•
•
0 = Software clears the bit by writing a 1 to it.
•
1 = This bit is set when the AHB Device would normally assert the PME# signal
independent of the state of the PME Enable bit (bit 8 in this register).
