Advanced Configuration and Power Interface Specification

Advanced Configuration and Power Interface Specification
PinConfig can be one of PullDefault, PullUp, PullDown, PullNone or a vendor-supplied value in
the range 128-255. The bit field name _PPI is automatically created to refer to this portion of the
resource descriptor.
DebounceTimeout is an optional argument specifying the debounce wait time, in hundredths of
milliseconds. The bit field name _DBT is automatically created to refer to this portion of the
resource descriptor.
ResourceSource is a string which uniquely identifies the GPIO controller referred to by this
descriptor. ResourceSource can be a fully-qualified name, a relative name or a name segment that
utilizes the namespace search rules.
ResourceSourceIndex is an optional argument and is assumed to be 0 for this revision.
ResourceUsage is an optional argument and is assumed to be ResourceConsumer for this revision.
DescriptorName is an optional argument that specifies a name for an integer constant that will be
created in the current scope that contains the offset of this resource descriptor within the current
resource template buffer. The predefined descriptor field names may be appended to this name to
access individual fields within the descriptor via the Buffer Field operators.
VendorData is an optional argument that specifies a RawDataBuffer containing vendor-defined byte
data to be decoded by the OS driver. The bit field name _VEN is automatically created to refer to
this portion of the resource descriptor.
PinList is a list of (zero-based) pin numbers on the ResourceSource that are described by this
descriptor. For interrupt pin descriptors, only one pin is allowed. The bit field name _PIN is
automatically created to refer to this portion of the resource descriptor.
Description
The GpioInt macro evaluates to a buffer that contains a GPIO Interrupt Connection resource
descriptor. The format of the GPIO Interrupt Connection resource descriptor can be found in "GPIO
Connection Descriptor" (Section 6.4.3.8.1). The macro is designed to be used inside of a Resource
Template (Section 19.3.3).
19.6.55 GpioIo (GPIO Connection IO Resource Descriptor Macro)
GpioIo (Shared, PinConfig, DebounceTimeout, DriveStrength, IORestriction, ResourceSource,
ResourceSourceIndex, ResourceUsage, DescriptorName, VendorData) {PinList}
Arguments
Shared is an optional argument and can be either Shared or Exclusive. If not specified, Exclusive is
assumed. The bit field name _SHR is automatically created to refer to this portion of the resource
descriptor.
PinConfig can be one of PullDefault, PullUp, PullDown, PullNone or a vendor-supplied value in
the range 128-255. The bit field name _PPI is automatically created to refer to this portion of the
resource descriptor.
DebounceTimeout is an optional argument specifying the hardware debounce wait time, in
hundredths of milliseconds. The bit field name _DBT is automatically created to refer to this portion
of the resource descriptor.
