Request Structure (eel_request_t) Settings

Basic operations such as reading from and writing to the data flash are performed by a single function. The

function transfers commands and data ID to the EEL via the request structure (eel_request_t). Furthermore, the

EEL state and error information are acquired via the request structure (eel_request_t).

In subsequent sections, write access to the request structure (eel_request_t) from the user is called user write

access, and read access to it from the user is called user read access.

Request Structure (eel_request_t)

The request structure (eel_request_t) is defined in the eel_types.h file. It should not be changed by the user.
