PRODUCTION DATA
The device interfaces to an external host using the SPI interface. The CC3120R device can interrupt the host using the HOST_INTR line to initiate the data transfer over the interface. The SPI host interface can work up to a speed of 20 MHz.
Figure 8-16 shows the SPI host interface.
Section 8.15.2.1 lists the SPI host interface pins.
