NOTE

Analog signals applied to digital gates can cause current flow from the positive to the

negative terminal. The throughput current flows if the analog signal is in the range of

transitions 0→1 or 1→0. The value of the throughput current depends on the driving

capability of the gate. For MSP430, it is approximately 100 µA.

Use P6SEL.x=1 to prevent throughput current. P6SEL.x should be set, if an analog signal

is applied to the pin.
