7. External Interfaces

7.1 Interfacing with the Host Microcontroller

This section describes interfacing the ATWINC15x0-MR210xB module with the host microcontroller. The

interface is comprised of a slave SPI and additional control signals, as shown in the following figure. For

more information on SPI interface specification and timing, refer to the SPI Interface. Additional control

signals are connected to the GPIO/IRQ interface of the microcontroller.
