11. ACPI REGISTERS FEATURES
W83977EF/EG supports both ACPI and legacy power managements. The switch logic of the power
management block generates an SMI# interrupt in the legacy mode and an SCI# interrupt in the ACPI
mode. The new ACPI feature routes SMI#/SCI# logic output either to SMI# or toSCI#. The SMI#/SCI#
logic routes to SMI# only when both SCI_EN = 0 and SMISCI_OE = 1.Similarly, the SMI#/SCI#
logicroutes to SCI# only when both SCI_EN = 1 and SMISCI_OE = 1.
