The PWM macrocell controls several channels independently. Each channel controls one
square output waveform. Characteristics of the output waveform such as period, duty-cycle and
polarity are configurable through the user interface. Each channel selects and uses one of the
clocks provided by the clock generator. The clock generator provides several clocks resulting
from the division of the PWM macrocell master clock.
All PWM macrocell accesses are made through registers mapped on the peripheral bus.
Channels can be synchronized, to generate non overlapped waveforms. All channels integrate a
double buffering system in order to prevent an unexpected output waveform while modifying the
period or the duty-cycle.
7 Channels
One 20-bit Counter Per Channel
Common Clock Generator Providing Thirteen Different Clocks
Independent Channels
– A Modulo n Counter Providing Eleven Clocks
– Two Independent Linear Dividers Working on Modulo n Counter Outputs
– Independent Enable Disable Command for Each Channel
– Independent Clock Selection for Each Channel
– Independent Period and Duty Cycle for Each Channel
– Double Buffering of Period or Duty Cycle for Each Channel
– Programmable Selection of The Output Waveform Polarity for Each Channel
– Programmable Center or Left Aligned Output Waveform for Each Channel
