Occasional ContributorHi Hareesh,
I finally have access to my account again.
I can't view the image in your message above, only the link to the manual.
Keep in mind that I am using version 18.1 instead of 21 that the link points to.
I have tried to set the different configuration registers to setup the IP in quad mode. But my problem is that however I do it, either the IP or the chip is behind on the mode change since I can't change both at the same time. And when they are not configured the same the code does not run from flash.
Regards,
Rienk
