35.4.16.1 Automatic fault clearing
If the automatic fault clearing is selected (FAULTM[1:0] = 1:1), then the channels output
disabled by fault control is again enabled when the fault input signal (FAULTIN) returns
to zero and a new PWM cycle begins. See the following figure.

35.4.16.2 Manual fault clearing
If the manual fault clearing is selected (FAULTM[1:0] = 0:1 or 1:0), then the channels
output disabled by fault control is again enabled when the FAULTF bit is cleared and a
new PWM cycle begins. See the following figure.
