The system power consumption is influenced by the number of enabled
modules and their functions. Disabling a module from the actual operation
mode reduces power consumption while other parts of the controller remain
fully active (unused pins must be tied appropriately or power consumption will
increase; see
Basic Hints for Low Power Applications in section 3.6.
