EN_ACPI status bit
= 0 Particular ACPI functions are disabled.
= 1 Particular ACPI functions are enabled.
The bit is strapped by Pin 70 (GP55). While particular ACPI functions are
enabled (EN_ACPI = 1), GPIO3 pins (pins 64, 69, 87, 91 and 92) are
disabled and the particular ACPI functions are activated (SUSC#,
FTPRST#, ATXPGD, VSBGATE# and PWROK2)
* This bit is available both for UBE and UBF version
EN_GTL Configure bit
= 0 VID input voltage is TTL.
= 1 VID input voltage is GTL.
The bit is strapped by Pin 77 (GP50).--- Internal Pull high to 3VSB.
EN_PWRDN. (VBAT)
= 0 Thermal shutdown function is disabled.
= 1 Enable thermal shutdown function.
