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

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.
