Note: Not implemented in the MSP430x43x1 and MSP430x44x1 devices
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, even if the signal at the pin is not being used by the ADC12.
