Introduction
34.1.1 Overview
The Voltage Reference provides a buffered reference voltage with high output current for
use as an external reference. In addition, the buffered reference is available internally for
use with on chip peripherals such as ADCs and DACs. Refer to the chip configuration
chapter for a description of these options. The reference voltage is output on a dedicated
output pin when the VREF is enabled. The Voltage Reference output can be trimmed
with a resolution of 0.5mV by means of the TRM register TRIM[5:0] bitfield.
34.1.2 Features
The Voltage Reference has the following features:
