enum tenuNmState

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 nm_get_state and checking against the desired state, it is possible to validate whether it is safe to proceed with SPI Flash access.

Enumerator
NM_STATE_DEINIT	WINC is not initialized
NM_STATE_INIT	WINC has been initialized. SPI flash access is possible.
NM_STATE_START	WINC has started

sint8 nm_cpu_start
