PCIE_CLKREQ_L
OD PCIe clock request signal which indicates when the
REFCLK to the PCIe interface can be gated.
1 = the clock can be gated
0 = the clock is required

PCIE_PME_L
OD PCI power management event output. Used to
request a change in the device or system power state.
The assertion and deassertion of this signal is
asynchronous to the PCIe reference clock. This signal
has an open-drain output structure, as per the PCI
Bus Local Bus Specification, revision 2.3.
