0008 help
0009 The "Serial Peripheral Interface" is a low level synchronous
0010 protocol. Chips that support SPI can have data transfer rates
0011 up to several tens of Mbit/sec. Chips are addressed with a
0012 controller and a chipselect. Most SPI slaves don't support
0013 dynamic device discovery; some are even write-only or read-only.
0014
0015 SPI is widely used by microcontrollers to talk with sensors,
0016 eeprom and flash memory, codecs and various other controller
0017 chips, analog to digital (and d-to-a) converters, and more.
0018 MMC and SD cards can be accessed using SPI protocol; and for
0019 DataFlash cards used in MMC sockets, SPI must always be used.
0020
0021 SPI is one of a family of similar protocols using a four wire
0022 interface (select, clock, data in, data out) including Microwire
0023 (half duplex), SSP, SSI, and PSP. This driver framework should
0024 work with most such devices and controllers.

1080 This simple SPI master controller is built into xtfpga bitstreams
1081 and is used to control daughterboard audio codec. It always transfers
1082 16 bit words in SPI mode 0, automatically asserting CS on transfer
1083 start and deasserting on end.

1114 help
1115 This adds support for SPI multiplexers. Each SPI mux will be
1116 accessible as a SPI controller, the devices behind the mux will appear
1117 to be chip selects on this controller. It is still necessary to
1118 select one or more specific mux-controller drivers.
