X - 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. Table 8 shows the PWM fre-
quencies for different resolutions. The level of the
output signals is selectable and the PWM module
can generate interrupt requests.
