33 * this 'structure' is a packed representation of an IO register 'bit'
34 * (or consecutive bits). This allows a way to set/get/clear them.
35 * gcc is happy passing these as register value, so you don't need to
36 * use a pointer when passing them along to functions.
38 * 9 bits ought to be enough, as it's the maximum I've seen (atmega2560)
