8Eh RESERVED BMON2 2 BMON2 1 BMON2 0 RESERVED PMON2 2 PMON2 1 PMON2 0
BIT 7 BIT 0
Allows for right-shifting the final answer of BMON2 and PMON2 voltage measurements. This allows for scaling the
measurement to the smallest full-scale voltage and then right-shifting the final result so the reading is weighted to the
correct LSB.
