Detailed Description

This 'structure' is a packed representation of an IO register 'bit' (or consecutive bits).

This allows a way to set/get/clear them. GCC is happy passing these as register value, so you don't need to use a pointer when passing them along to functions.

9 bits ought to be enough, as it's the maximum I've seen (atmega2560)
