11.0
The Voltage Reference module consists of a 16-tap
resistor ladder network that provides a selectable volt-
age reference. The resistor ladder is segmented to pro-
vide two ranges of V
function to conserve power when the reference is not
being used. The VRCON register controls the opera-
tion of the reference as shown in Figure 11-1. The
block diagram is given in Figure 11-1.
11.1
The Voltage Reference module can output 16 distinct
voltage levels for each range.

The equations used to calculate the output of the
Voltage Reference module are as follows:
The setting time of the Voltage Reference module must
be considered when changing the V
(Table 17-3). Example 11-1 demonstrates how voltage
