(4) See Typical Characteristic curves.
(5) Note that the numbers in the brackets correspond to the REFSEL number and its value. For example, in this case, REFSEL [0,0] means
that REFSEL1 = 0 and REFSEL2 = 0.
(6) OR and ERROR are open-drain outputs. No internal pull-up resistor. Output voltage depends on the external pull up resistor that is
used.
