Description
Reserved
GPIO[7:4] Sticky Mask: Not Supported.
GPIO[3:0] Sticky Mask: Defines GPIO Input
Type (0 = Non-Sticky, 1 = Sticky) when a GPIO
pin is configured as an input. GPIO inputs config-
ured as Sticky are cleared by writing a 0 to the
corresponding bit of the GPIO Data Control
The default value for these bits (0h) is all pins
Non-Sticky. Non implemented GPIO pins always
return 0’s. Sticky is defined as Positive-Edge
sensitive, Non-Sticky as Level sensitive.
6.3.13 Implementation Identification
This field provides the Board Implementation ID and Assembly ID of the functional group to software. It is a
Read/Write-Once register; BIOS writes to this field to configure the Board Implementation ID and Assembly ID during
the boot process.
