Description
BIOS_RLS
The BIOS release bit. This bit is used by the BIOS software to raise an event
to the ACPI software. The ACPI software has a corresponding enable and
status bit to control its ability to receive the ACPI event. Setting BIOS_RLS
sets GBL_STS, and it generates an SCI
interrupt if GBL_EN is also set.
Writing a 1 to its bit position sets this bit and also sets the BM_STS bit.
Writing a 0 has no effect. This bit is cleared by writing a 1 to the GBL_STS
bit.
This bit is used to set the BM_STS bit and if the BM_RLD bit is also set, then
an SCI interrupt is generated. Writing a 1 sets BM_CNTRL to 1 and also sets
BM_STS. Writing a 0 has no effect. Wrinting a 1 to BM_STS clears
BM_STS and also clears BM_CNTRL.
