4.11.2.1 SPI
4.11.2.1.1 SPI Master
The CC3200 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 4-9 shows the timing diagram for the SPI master.
