Alternate GPI SMI Enable — R/W. These bits are used to enable the corresponding GPIO to cause
an SMI#. For these bits to have any effect, the following must be true.
NOTE: Mapping is as follows: bit 15 corresponds to GPI[15] ... bit 0 corresponds to GPI[0].
Alternate GPI SMI Status — R/WC. These bits report the status of the corresponding GPIs.
0 = Inactive. Software clears this bit by writing a 1 to it.
1 = Active
These bits are sticky. If the following conditions are true, then an SMI# will be generated and the
GPE0_STS bit set:
All bits are in the resume well. Default for these bits is dependent on the state of the GPI pins.
• The corresponding bit in the ALT_GP_SMI_EN register is set.
• The corresponding GPI must be routed in the GPI_ROUT register to cause an SMI.
• The corresponding GPIO must be implemented.
• The corresponding bit in the ALT_GPI_SMI_EN register (PMBASE + 38h) is set
• The corresponding GPI must be routed in the GPI_ROUT register to cause an SMI.
• The corresponding GPIO must be implemented.
