-/** \addtogroup efc_module Working with EEFC
- * The EEFC driver provides the interface to configure and use the EEFC
- * peripheral.
- *
- * The user needs to set the number of wait states depending on the frequency used.\n
- * Configure number of cycles for flash read/write operations in the FWS field of EEFC_FMR.
- *
- * It offers a function to send flash command to EEFC and waits for the
- * flash to be ready.
- *
- * To send flash command, the user could do in either of following way:
- * <ul>
- * <li>Write a correct key, command and argument in EEFC_FCR. </li>
- * <li>Or, Use IAP (In Application Programming) function which is executed from
- * ROM directly, this allows flash programming to be done by code running in flash.</li>
- * <li>Once the command is achieved, it can be detected even by polling EEFC_FSR or interrupt.
- * </ul>
- *
- * The command argument could be a page number,GPNVM number or nothing, it depends on
- * the command itself. Some useful functions in this driver could help user tranlate physical
- * flash address into a page number and vice verse.
- *
- * For more accurate information, please look at the EEFC section of the
- * Datasheet.
