Port P6, P6.6 Input/Output With Schmitt Trigger
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.
