Other attachments are machine-dependent and will depend on the bus topology of your system. See intro(4) for your system for more information.
Your system may support additional machine-dependent SPI devices. Consult your system's intro(4) for additional information.
SPI is a 4-wire synchronous full-duplex serial bus. Some systems provide support for Microwire, which is Philips' name for a strict subset of SPI, with more rigidly defined signaling. Therefore, Microwire devices are also supported by the SPI framework.
Note that when referencing SPI devices in a config(1) file, the ‘slave' must be provided, as SPI lacks any way to automatically probe devices.
