Revision 1.1
Register Descriptions (Continued)
1
OEM_GPE_E01: Original Equipment Manufacturer General Purpose Event Enable Bit 1 - When set, enables a SCI to be
generated when the corresponding GPE0_STS bit is set.
0
OEM_GPE_E00: Original Equipment Manufacturer General Purpose Event Enable Bit 0 - When set, enables a SCI to be
generated when the corresponding GPE0_STS bit is set.
ACPI_BASE 14h-17h
SETUP_DATA — Setup Data Register (R/W)
Reset Value = 00000000h
During a read operation, SETUP_DATA returns the value of the internal setting specified by the current value in SETUP_IDX
(ACPI_ABASE 0Eh-0Fh)
ACPI_BASE 18h-1Fh
Reserved
Reset Value = 00h
Reserved for future V-ACPI Implementations.
