24.8.4 Quick Start Guide for TC - Callback

In this use case, the TC will be used to generate a PWM signal, with a varying duty cycle. Here the pulse width is increased each time the timer count matches the set compare value. The TC module will be set up as follows:

  • GCLK generator 0 (GCLK main) clock source

  • 16-bit resolution on the counter

  • No prescaler

  • Normal PWM wave generation

  • GCLK reload action

  • Don't run in standby

  • No inversion of waveform output

  • No capture enabled

  • Count upward

  • Don't perform one-shot operations

  • No event input enabled

  • No event action

  • No event generation enabled

  • Counter starts on 0
