13.0 Voltage Reference (VREF)
13.1 Voltage Reference Overview
The SLG46121 has a Voltage Reference Macrocell to provide references to the four analog comparators. This macrocell can
supply a user selection of fixed voltage references, /3 and /4 reference off of the VDD power supply to the device, and externally
supplied voltage references from Pin 4. The macrocell also has the option to output reference voltages on pins 10. See table
below for the available selections for each analog comparator. Also see Figure 45 below, which shows the reference output
structure.
