Description
SCI_EN
Select whether the power management event triggers an SCI
or an SMI
interrupt. When this bit is set, then the power management events will
generate an SCI
interrupt. When this bit is reset and SMI_EN bit is set, then
the power management events will generate an SMI
interrupt.
This is the bus master reload enable bit. If this bit is set and BM_CNTRL is
set, an SCI
interrupt is raised.
The global release bit. This bit is used by the ACPI software to raise an event
to the BIOS software. The BIOS software has a corresponding enable and
status bit to control its ability to receive the ACPI event. Setting GBL_RLS
sets BIOS_STS, and it generates an SMI
interrupt if BIOS_EN is also set.
Reserved. These bits always return zeros.
