Overview
XMEGA A4 has an advanced clock system, supporting a large number of clock sources. It incor-
porates both integrated oscillators, external crystal oscillators and resonators. A high frequency
Phase Locked Loop (PLL) and clock prescalers can be controlled from software to generate a
wide range of clock frequencies from the clock source input.
It is possible to switch between clock sources from software during run-time. After reset the
device will always start up running from the 2 Mhz internal oscillator.
A calibration feature is available, and can be used for automatic run-time calibration of the inter-
nal 2 MHz and 32 MHz oscillators. This reduce frequency drift over voltage and temperature.
A Crystal Oscillator Failure Monitor can be enabled to issue a Non-Maskable Interrupt and
switch to internal oscillator if the external oscillator fails. Figure 10-1 on page 19 shows the prin-
cipal clock system in XMEGA A4.
