Hi all, I've seen a few different ways to do this, and I'm not sure if there are better or worse ways on this one. I am working in XC8, and I want to be able to set multiple bits in a register at once. In assembly, I'd mask off the bits I wanted to effect with an AND, then OR in my desired value. For example, if I had a register called target, and I wanted to modify bits 2 and 3, I'd first AND target with b'11110011', then take the data I wanted to put in there (in this case b'11'), and OR target with b'00001100'. Can I combine these commands in C? Or is there a better way? I think I coul= d do: target |=3D 0b11110011; target &=3D 0b00001100; But what about: target =3D (target | 0b11110011) & 0b00001100; Thanks!
