    The synchronization primitives used in the latest reference implementation have been updated to use Zephyr spinlocks instead of semaphores.

+   The IRQ for nRF70 Series is configued as a GPIO pin, and is Edge triggered i.e., interrupt to be triggered on pin state change to logical level 1.

 * *Driver model*: The reference implementation uses the Zephyr driver model to manage the nRF70 Series device.
