5.19.5.1 SPI

5.19.5.1.1 SPI Master

The CC3235MODAx MCU 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 5-13 lists the timing parameters for the SPI master.
