3.6 PWM Module
The Pulse Width Modulation Module can generate up to four PWM output signals using
edge-aligned or center-aligned PWM. In addition the PWM module can generate PWM
burst signals and single shot outputs. The frequency range of the PWM signals covers
4 Hz to 16.5 MHz (referred to a CPU clock of 33 MHz), depending on the resolution of
the PWM output signal. The level of the output signals is selectable and the PWM
module can generate interrupt requests.
