near the GND or VDD supply rails. The P1.6 setting for the positive input should be used in conjunction with
the selection of P2.0 as the negative input. P1.6 should be configured for push-pull mode and driven to the
desired supply rail. Although P1.6 is not connected to a device pin in these packages, it is still a valid signal
internally.
