VLP(SVS)=15

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.

NOTE: The signal at pins P6.x/Ax is used by the 12-bit ADC module.

The signal at pin P6.7/A7/SVSIN is also connected to the input multiplexer in the module brownout/supply voltage supervisor.
