the Msp430Adc12SingleChannel allows to perform one or more ADC conversions on a
single channel with a specified sampling frequency and (2) the
Msp430Adc12MultiChannel allows to sample a group of up to 16 different ADC
-channels "at once" (with minimum latency) and in addition define a sampling
-frequency for the whole group (useful for multi-channel accelerometers, etc.).

On the MSP430 two additional hardware modules may play a role when the ADC12 is
used: the internal reference voltage generator and the DMA controller.
