The LRADC control register 2 provides control over the shared eight channel LRADC
converter. It allows software to independently schedule conversion cycles on any number
of any size subsets of the eight channels. In addition it allows software to manage the
interrupt reporting for the channel conversion sets.

Each bit of this eight bit field corresponds to a channel of an LRADC. Setting the bit to one caused the A/D
converter to use its analog divide by two circuit for the conversion of the corresponding channel.
