Variations: Variations has nothing to do with lack of standards; a standard could allow for variations
As my college professor told me: don't put important info in footnotes. KISS
Line 35:
Typical [[#Applications|applications]] include interfacing [[microcontrollers]] with peripheral chips for [[Secure Digital]] cards, [[liquid crystal display]]s, [[analog-to-digital]] and [[digital-to-analog converters]], [[Flash memory#Serial flash|flash]] and [[EEPROM#Serial bus devices|EEPROM]] memory, and various communication chips.
 
Although SPI may be accurately described asis a synchronous serial interface,<ref>{{cite web |url= https://digital.ni.com/public.nsf/allkb/862567530005F09C862566BE004E469D |title= What is Serial Synchronous Interface (SSI)? |access-date= 2015-01-28 }}</ref> but it is different from the [[Synchronous Serial Interface]] (SSI) protocol.{{NoteTag|While [[Synchronous Serial Interface]] (SSI) isBoth alsoare a four-wire synchronous serial communication protocolprotocols, thebut SSI protocol employs [[differential signaling]] and provides only a single [[simplex communication]] channel.}}
