A simple class that will be instantiated by default when a sub block is defined without another class name specified

This class includes support for registers, pins, etc.

#_resolve_controller_class, #add_configuration, #add_mode, #configuration, #configuration=, #configurations, #current_configuration, #current_mode, #current_mode=, #delete_all_modes, #delete_all_specs_and_notes, #find_specs, #has_mode?, #ip_name, #log, #modes, #read_memory, #with_configuration, #with_each_mode, #with_mode, #wrap_in_controller, #write_memory

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *args, &block) ⇒ Object

Used to create attribute accessors on the fly.

On first call of a missing method a method is generated to avoid the missing lookup next time, this should be faster for repeated lookups of the same method, e.g. reg
