3.5 Suspend / Resume mechanism
Some Data Flash operations can last a long time especially multiple erase and write. The user application
cannot always wait for the operation end because other operations have higher priority. So, from user
point of view current operation is suspend-able and can be resumed after finishing the other Flash
accesses.
From software point of view an on-going operation always ends in suspended state unless the resume is
requested beforehand. In case the Flash hardware has already finished an operation but its end result
has not already been processed by the library, the library returns the suspended status. The final
operation result is returned after successful resume request.
The FDL contains special functions to suspend and resume an ongoing operation. Please refer to chapter
4.4.3.1 “R_FDL_SuspendRequest”.
