Configuring the Voltage Reference
The Voltage Reference can output 16 distinct voltage levels for each range.
The equations used to calculate the output of the Voltage Reference are as follows:
The settling time of the Voltage Reference must be considered when changing the V

some error since VR3:VR0 can only be an integer, and the V
so that the result is not greater then 15.
Equation 19-1:

When VRR = 0
if VRR = 1: V
