11 - PWM MODULE
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 13 shows the PWM
frequencies for different resolutions. The level of
the output signals is selectable and the PWM
module can generate interrupt requests.
