@brief
    Enumeration for WINC state
    The following is used to track the state of the WINC (not initialized, initialized or started)

@remarks
    This is useful when putting the WINC in "download mode" to access the flash via SPI. By using
    @ref nm_get_state and checking against the desired state, it is possible to validate whether
    it is safe to proceed with SPI Flash access.
