8.14.5.1 SPI
8.14.5.1.1 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.
