= 1 RSTOUT3# (Default)
Note: This bit is ignored when CR2A, bit 1 is High.
Pin 90 Select
5
R/W
= 0 GP32
= 1 RSTOUT2# (Default)
Note: This bit is ignored when CR2A, bit 1 is High.
EN_ACPI status bit
= 0 Particular ACPI functions are disabled.
= 1 Particular ACPI functions are enabled.

Read Only ^{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.
