CLKREQ# PCIe Clock Request is a reference clock request signal as defined by the PCI Express Mini
CEM Specification. This signal is also used by L1PM Substates. Open Drain with pull up on
Platform. Active Low.

PEWAKE# PCIe WAKE#. Open Drain with pull up on Platform. Active Low when used as PEWAKE#.
When the Adapter supports wakeup, this signal is used to request that the system return
from a sleep/suspend state to service a function-initiated wake event. When the Adapter
supports OBFF mechanism, the PEWAKE#signal is used for OBFF signaling.
