Most all of my simple sketches seem to run on my due. However I have not found out how to go into a register and modify a single bit yet, I would dearly love to go to 0x40094000 and change bit# 19 to a zero.
I have been trying with word, bitWrite, and bitClear with no success. Bit read seems to work and the write protect register seems to be off for this byte. All I want to do is change one bit. Getting a little frustrated. Might have to box the due until there is more docks and stuff. The mega 2560 has no problem with simple stuff like this.
