Allows for right-shifting the final answer of MON1 and MON2 voltage measurements. This allows for scaling the
measurements to the smallest full-scale voltage and then right-shifting the final result so the reading is weighted
to the correct LSB.

Allows for right-shifting the final answer of MON3 and MON4 voltage measurements. This allows for scaling the
measurements to the smallest full-scale voltage and then right-shifting the final result so the reading is weighted
to the correct LSB. The MON3 right-shifting is only available for the fine mode of operation. The coarse mode does
not right-shift.
