The SPI bus controller enables communications with a variety of peripherals such as memories, temperature sensors, pressure sensors, analog converters, real-time clocks, displays, and any SD card with serial mode support. The SPI controller can function in master mode with multi-master feature, slave mode, or loopback test mode.

There are two instances of the SPI controller. Both the controllers are identical and independent. The SPI controllers are located in the LPD power domain of the PS.

The I/O interfacing options include the PMC and LPD MIO pins.

Software accesses the control and status registers via the APB slave programming interface on the LPD IOP switch.
