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