12.4.14.2 Manual fault clearing
If the manual fault clearing is selected (FAULTM[1:0] = 0:1 or 1:0), then disabled
channel outputs are enabled when the FAULTF bit is cleared and a new PWM cycle
begins. See the following figure.
It is possible to manually clear a fault by clearing the FAULTF bit, and enable disabled
channels regardless of the fault input signal (FAULTIN) (the filter output if the filter is
enabled or the synchronizer output if the filter is disabled). However, it is recommended
to verify the value of the fault input signal (value of the FAULTIN bit) before clearing
the FAULTF bit to avoid unpredictable results.

12.4.15 Polarity control
The POLn bit selects the channel (n) output polarity:
• If (POLn = 0), the channel (n) output polarity is active-high: one is the active state;
zero is the inactive state.
• If (POLn = 1), the channel (n) output polarity is active-low: zero is the active state;
one is the inactive state.
