Could you let me get an example code and project for controlling external memory by system bus?
Thanks for reaching out to Renesas Engineering Community.
There is not an example project for controlling external bus. Controlling of the external bus is done at register level (no APIs) and it depends on your application and the external device. I have made a quick project with some initial code so you can get started. Please note that these settings are just some random settings and you would need to match the settings to the actual timings of your device. Section 15 of User's Manual contains all the needed information about external bus settings.
Appriciate your help.
