Note 1. This pin becomes OVF pin when OVFE bit is set to “1”.
Note 2. This pin becomes DZF pin when OVFE bit is set to “0”.
Note 3. This pin becomes analog negative input pin in differential input mode, and becomes output pin invert the positive
input pin in single-end input mode. This pin must be open in single-end input mode.
Note 4. All digital input pins except for pull-down must not be left floating.
