11 - PWM MODULE

11.1 - Standard 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.
