5.14.5.1 SPI

5.14.5.1.1 SPI Master

The CC3220MODx and CC3220MODAx microcontroller includes one SPI module, which 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 5-8 shows the timing diagram for the SPI master.

Figure 5-8. SPI Master Timing Diagram

Table 5-4 lists the timing parameters for the SPI master.
