4 Software Description

The software provided with this application report includes EEPROM Emulation source code for the F29H85 Real-Time Controller with an example project demonstrating how to utilize the source code.

This software provides basic EEPROM functionality: write, read, and erase. At least one sector of Flash memory is used to emulate EEPROM. This sector(s) is broken into several EEPROM banks and pages, each containing status words to determine the validity of the data as described above.

This code uses the Header Files and Flash API libraries provided for the F29H85x. The example code can be found within the F29H85x SDK Directory. The full path is: f29h85x-sdk_1_00_00_00\examples\driverlib\single_core\flash
