Causes of SMI# (Sheet 1 of 2)
NOTES:
Enhanced USB Legacy Support
Classic USB Legacy logic (IRQ)
1. GBL_SMI_EN must be 1 to enable SMI.
2. EOS must be written to 1 to re-enable SMI for the next one.
3. Some SMI#s are considered “synchronous”, in that the processor should recognize the SMI#
4. NMI2SMI_STS is not gated by TCO_EN.
Internal EHCI wake (PME_B0)

prior to completing the instruction (I/O read, I/O write, Memory read, or Memory write) that
should cause the SMI#. This is accomplished by having the SMI# signal go active to the
processor prior to the processor observing the RDY# signal that terminates the cycle. SMI#s
marked with X in the Synch column are treated as Synchronous.Synchronous SMI#s are not
possible in IA64 platforms, since they do not support the SMI# signal.
