Title:
XMEGA Internal RC Oscillator Calibration
Name:

Author:

Description:
This application note describes a fast and accurate way of calibrating the internal RC oscillators on XMEGA® devices. An easily adaptable calibration firmware example is available through Atmel® START, which can be used with any XMEGA with one or more tunable internal RC oscillators and a JTAG interface. The routine is based on using an AVR programming tool for generating a reference clock signal at a known frequency and comparing this to the frequency of the internal RC oscillator.
