These functions are generally 1 machine instruction, and are used in critical code, so makes sense to have them inline. Also leave these functions uninverted (ie 0 means enable, 1 means disable) and provide macro constants if you really need to distinguish the states. This makes for smaller code as well (combined with inlining). Applied to teensy port as well.
