XMEGA has a set of high-end and very flexible 16-bit Timer/Counters (TC). Their basic capabili-
ties include accurate program execution timing, frequency and waveform generation, event
management, and time measurement of digital signals. The Hi-Resolution Extension (Hi-Res)
and Advanced Waveform Extension (AWeX) can be used together with a Timer/Counter to ease
implementation of more advanced and specialized frequency and waveform generation
features.

ules (in grey) is shown in
