5.14.5 Peripherals Timing
This section describes the peripherals that are supported by the CC3220MODx and CC3220MODAx
modules, as follows:
• SPI
• I2S
• GPIOs
• I²C
• IEEE 1149.1 JTAG
• ADC
• Camera parallel port
• External Flash

• SD Host
• Timers
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.
