FLTDAT<1:0>: State for PWMxH and PWMxL Pins if FLTMOD is Enabled bits
FCLCONx<IFLTMOD> = 0: Normal Fault mode:
If Fault is active, then FLTDAT<1> provides the state for PWMxH
If Fault is active, then FLTDAT<0> provides the state for PWMxL
If Fault is active, then FLTDAT<1> provides the state for PWMxH
If Fault is active, then FLTDAT<0> provides the state for PWMxL
FCLCONx<IFLTMOD> = 1: Independent Fault mode:
If current-limit is active, then FLTDAT<1> provides data for PWMxH
If Fault is active, then FLTDAT<0> provides the state for PWMxL
If current-limit is active, then FLTDAT<1> provides data for PWMxH
If Fault is active, then FLTDAT<0> provides the state for PWMxL
Note 1:
These bits should be changed only when PTEN = 0. Changing the clock selection during operation will
yield unpredictable results.
