I could understand The CLKREQ# signal is used by the L1 PM Substates mechanism. And PEWAKE signal is used to wake up the ROOT COMPLEX(RC) during the sleep mode. And these two signals are bidirectional signals.
During Bifurcation, I want to know how these signals have to be maintained electrically. For other sideband signals(REFCLK and PERST) I have used a buffer and connected.
Can anyone help me?
