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.
