Serial Peripheral Interface (SPI) Slave
The SPI Slave provides an industry-standard, 4-wire slave SPI interface. It can also provide a 3-wire (bidirectional) SPI interface. Both interfaces support all four SPI operating modes, allowing communication with any SPI master device. In addition to the standard 8-bit word length, the SPI Slave supports a configurable 3- to 16-bit word length for communicating with nonstandard SPI word lengths.
