* Connect the radiation PAD in solder side of the package and analog ground (AVSS) for the
exothermicity improvement.
(note 1) It will be input on DC mode, be Hi-Z on CCD mode.
(note 2) Please be input state.
(note 3) It will be H or L since PD mode.
(note 4) It is connect with AVSS via internal resistance.
