NET+50 development board

Hello, I have revision D of this development board. Beside the switches 5 and 6 on the SW4 is written FBANK1 and FBANK2. In the documentation (for example doc Jumpers and Components guide) I’ve read that FWRITE and FREAD switches are on these positions. What is the actual purpose of these switches on the NET+50 Rev D boards? How can I disable flash writing on this board?

If on your board if you have FBANK then set them to off to disable the flash.
