void S_Nv_EarlyInit

(

void

)

Initializes the internal flash service for early access.

Note

It is not required to call this function if the application does not require early access to internal Nv. Note that the S_Nv component is fully functional after calling S_Nv_EarlyInit(), but until S_Nv_Init() is called, chances are much higher that the component blocks when a sector becomes full. Only after S_Nv_Init() is called, compacting the sector is decoupled as much as possible.
