The ADC is controlled by an ADC control register. Several modes of operation are possible, depending upon
the bits set in the control register. Channel selection, scan operation, averaging, resolution, and conversion rate
may all be programmed through this register. These modes are outlined in the sections below for each type of
analog input. The results of conversions made are stored in the appropriate result register.
