(1) Write to each bit (except bit 6) of A-D control register 0, to each bit of A-D control register 1,
(2) To reduce conversion error due to noise, connect a voltage to the AVcc pin and to the Vref pin from
(3) Set the direction register of the following ports to input: the port corresponding to a pin to be
