The PEP_ACPI_INITIALIZE_SPB_SPI_RESOURCE function initializes a platform extension plug-in's (PEP) PEP_ACPI_SPB_SPI_RESOURCE structure.
DeviceSelection [in]The device selection value. This value is specific to the device and may refer to a chip-select line, GPIO line, or other line selection mechanism.
DeviceSelectionPolarity [in]The polarity of the clock. If zero, this indicates the clock is low during the first phase. If 1, this indicates the clock is high during the first phase.
WireMode [in]When zero, indicates that this device produces and consumes this resource. Otherwise, this device only consumes this resource.
DataBitLength [in]The size, in bits, of the smallest unit of transfer.
SlaveMode [in]Indicates if the resource is operating in slave mode.
ConnectionSpeed [in]The maximum speed, in hertz, supported by this connection.
ClockPolarity [in]The polarity of the clock. If zero, this indicates the clock is low during the first phase. If 1, this indicates the clock is high during the first phase.
ClockPhase [in]The phase of the clock pulse on which to capture data.
ResourceSource [in]The name of the serial bus controller device to which this connection descriptor applies. The name can be a fully qualified path, a relative path, or a simple name segment that utilizes the namespace search rules.
ResourceSourceIndex [in]This parameter should always be set to zero.
ResourceUsage [in]Indicates if the resource is in use.
SharedMode [in]Indicates if the resource is shared.
VendorData [in]A pointer to optional data that is specific to the serial bus connection type.
VendorDataLength [in]The length of the buffer pointed to by the VendorData parameter.
Resource [out]A pointer to the resource. The structure behind the pointer is of type PEP_ACPI_SPB_SPI_RESOURCE.
