Preliminary data sheet

The PWMs can be used to generate waveforms in which the frequency, duty cycle and
rising and falling edges can be controlled very precisely. Capture inputs are provided to
measure event phases compared to the main counter. Depending on the applications,
these inputs can be connected to digital sensor motor outputs or digital external signals.
Interrupt signals are generated on several events to closely interact with the CPU.
The ADCs can be used for any application needing accurate digitized data from analog
sources. To support applications like motor control, a mechanism to synchronize several
PWMs and ADCs is available (sync_in and sync_out).
Note that the PWMs run on the PWM clock and the ADCs on the ADC clock, see
