PWM modules
Two pulse width modulation modules are available on ST10F272: standard PWM0 and
XBUS PWM1. They can generate up to four PWM output signals each, using edge-aligned
or centre-aligned PWM. In addition, the PWM modules can generate PWM burst signals and
single shot outputs. The Table 38 and Table 39 show the PWM frequencies for different
resolutions. The level of the output signals is selectable and the PWM modules can
generate interrupt requests.
