registers
(1): Registers that are common to all drawings can be called from any drawing or function.
(2): Registers that are unique to each drawing can be called only from within the drawing.
(3): Registers that are unique to each function can be called only from within the function.
(4): Registers that are common to all drawings and registers that are unique to each
drawing can be called from functions using the external function registers.
