Wiper placement for each potentiometer is such that position-63 corresponds to the H

terminal of the de-

vice while position-0 corresponds to the ground terminal. For example, to set a potentiometer’s wiper

position to 15 (decimal), the binary value shifted into the wiper register should be 00001111. This will

place the wiper tap at the 15

step above the low-end terminal, L

All communication transactions should provide the total 48 bits of information when writing or reading

from the part. This is especially true for applications using all six potentiometers. If a complete set of 48

bits is not transmitted to the part, undesired wiper position settings may occur.
