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 sin-
gle shot outputs. The Table 16 shows the PWM
frequencies for different resolutions. The level of
the output signals is selectable and the PWM
module can generate interrupt requests.
