ACPI REGISTERS FEATURES
W83697HF supports both ACPI and legacy power managements. The switch logic of the power
SMI PME
management block generates an
interrupt in the legacy mode and an
interrupt in the ACPI
mode. The new ACPI feature routes SMI / PME logic output either to SMI or toPME .The
SMI /PME logic routes to SMI only when both PME_EN = 0 and SMIPME_OE = 1. Similarly, the
SMI PME
PME
only when both PME_EN = 1 and SMIPME_OE = 1.
