A 1-channel Pulse Width Modulation (PWM) Module operates on channel 3. The pulse width
modulation module can generate up to four PWM output signals using edge-aligned or centre-
aligned PWM. In addition, the PWM module can generate PWM burst signals and single shot
outputs. The table below shows the PWM frequencies for different resolutions. The level of
the output signals is selectable and the PWM module can generate interrupt requests.
