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.
