Do I need to do anything to get voltage on my I/O pins on the ATSAM4LC2? I made a small program that just toggles pin PA20. On an ATSAM4LC4 it works fine, but if I do the same on a ATSAM4LC2 the IO pin just toggles if I put an external pullup on it.
I tried to enable pullup on the I/O control registers, but it didn't help. I am applying power to VDDIO and VLCDIN. Not sure what could be wrong. Tried everything I could think of already!
Thanks for your help!
