14.1.2. PWM Output Mode
If PWM output mode is selected, the output signal is a digital signal with Pulse Width Modulation (PWM).
The PWM polarity is selected by the PWMPOL parameter:
• PWMPOL = 1 for a low level at 100%
• PWMPOL = 0 for a high level at 100%
The PWM frequency is selected by the PWMT parameter. The following table provides typical code for
different target PWM frequency and for both low and high speed modes.

Notes:
• A more accurate trimming can be performed to take into account initial tolerance of the main
clock.
• The PWM frequency is subjected to the same tolerances as the main clock (see ∆^TCk).
