The LRADC control register 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.

When set to one, this bit causes a reset to the entire LRADC block. In addition, it turns off the converter
clock and powers down the analog portion of the LRADC. Set this bit to zero for normal operation.
This bit must be set to zero for normal operation. When set to one it gates off the clocks to the block.
Reserved
Set this bit to one to use the on-chip ground as reference for conversions.
