O

VSS ADC reference voltage; Negative side.

Connect capacitor0.1uF between AVSS and this pin.

And connect capacitor 1uF between VRP and this pin.

O

VSS ADC reference voltage; Positive side.

Connect capacitor0.1uF between AVSS and this pin.

And connect capacitor 1uF between VRN and this pin.

(note1) It is connect with VSS via internal resistance by CDS, Clamp mode or DC direct mode

(note2) Do not connect it anywhere.

(note3) When SDENB is Hi, it will be output condition as VSS. When SDENB is Low, it will be

input condition.
