Alternate GPI SMI Status — R/WC. These bits report the status of the corresponding
GPIOs.
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
GPIO pins.
Reserved
SWGPE_CTRL— R/W. This bit allows software to control the assertion of SWGPE_STS
bit. This bit is used by hardware as the level input signal for the SWGPE_STS bit in the
GPE0_STS register. When SWGPE_CTRL is 1, SWGPE_STS will be set to 1, and writes to
SWGPE_STS with a value of 1 to
clear SWGPE_STS will result in SWGPE_STS being set back to 1 by hardware. When
SWGPE_CTRL is 0, writes to SWGPE_STS with a value of 1 will clear SWGPE_STS to 0.
THRM#_POL — R/W. This bit controls the polarity of the THRM# pin needed to set the
THRM_STS bit.
0 = Low value on the THRM# signal will set the THRM_STS bit.
1 = HIGH value on the THRM# signal will set the THRM_STS bit.
• The corresponding bit in the ALT_GPI_SMI_EN register (PMBASE + 38h) is set
• The corresponding GPIO must be routed in the GPI_ROUT register to cause an SMI.
• The corresponding GPIO must be implemented.
