PWM modules
Two pulse width modulation modules are available on ST10F272M: standard PWM0 and
XBUS PWM1. They can generate up to four PWM output signals each, using edge-aligned
or center-aligned PWM. In addition, the PWM modules can generate PWM burst signals and
single shot outputs.
of the output signals is selectable and the PWM modules can generate interrupt requests.
