The CC3235x microcontroller includes one SPI module that can be configured as a master or slave device. The SPI includes a serial clock with programmable frequency, polarity, and phase; a programmable timing control between chip select and external clock generation; and a programmable delay before the first SPI word is transmitted. Slave mode does not include a dead cycle between two successive words.

Figure 8-13 shows the timing diagram for the SPI master.

Table 8-22 lists the timing parameters for the SPI master.
