98ae12a0dSDavid Brownell	  The "Serial Peripheral Interface" is a low level synchronous
108ae12a0dSDavid Brownell	  protocol.  Chips that support SPI can have data transfer rates
118ae12a0dSDavid Brownell	  up to several tens of Mbit/sec.  Chips are addressed with a
128ae12a0dSDavid Brownell	  controller and a chipselect.  Most SPI slaves don't support
138ae12a0dSDavid Brownell	  dynamic device discovery; some are even write-only or read-only.
148ae12a0dSDavid Brownell
153cb2fcccSMatt LaPlante	  SPI is widely used by microcontrollers to talk with sensors,
168ae12a0dSDavid Brownell	  eeprom and flash memory, codecs and various other controller
178ae12a0dSDavid Brownell	  chips, analog to digital (and d-to-a) converters, and more.
188ae12a0dSDavid Brownell	  MMC and SD cards can be accessed using SPI protocol; and for
198ae12a0dSDavid Brownell	  DataFlash cards used in MMC sockets, SPI must always be used.
208ae12a0dSDavid Brownell
218ae12a0dSDavid Brownell	  SPI is one of a family of similar protocols using a four wire
228ae12a0dSDavid Brownell	  interface (select, clock, data in, data out) including Microwire
238ae12a0dSDavid Brownell	  (half duplex), SSP, SSI, and PSP.  This driver framework should
248ae12a0dSDavid Brownell	  work with most such devices and controllers.
