1. Typical specifications are not guaranteed.

2. It is possible to remove Vdd, maintaining Vdd_IO without blocking the communication busses. In this condition the

measurement chain is powered off.

3. 4 mA is the maximum driving capability, ie. the maximum DC current that can be sourced/sunk by the digital pin in order to

guarantee the correct digital output voltage levels VOH and VOL.
