IFLTMOD: Independent Fault Mode Enable bit
1 = Independent Fault mode: Current-limit input maps FLTDAT<1> to PWMxH output and Fault input
maps FLTDAT<0> to PWMxL output; the CLDAT<1:0> bits are not used for override functions
0 = Normal Fault mode: Current-Limit mode maps CLDAT<1:0> bits to the PWMxH and PWMxL
outputs; the PWM Fault mode maps FLTDAT<1:0> to the PWMxH and PWMxL outputs.

These bits should be changed only when PTEN = 0. Changing the clock selection during operation will
yield unpredictable results.
When Independent Fault mode is enabled (IFLTMOD = 1) and Fault 1 is used for Fault mode
(FLTSRC<4:0> = 01000), the Current-Limit Control Source Select bits (CLSRC<4:0>) should be set to an
unused current-limit source to prevent the current-limit source from disabling both the PWMxH and
PWMxL outputs.
When Independent Fault mode is enabled (IFLTMOD = 1) and Fault 1 is used for Current-Limit mode
(CLSRC<4:0> = 01000), the Fault Control Source Select bits (FLTSRC<4:0>) should be set to an unused
Fault source to prevent Fault 1 from disabling both the PWMxL and PWMxH outputs.
