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 feature maps CLDAT<1:0> bits to the PWMxH and PWMxL
outputs. The PWM Fault feature maps FLTDAT<1:0> to the PWMxH and PWMxL outputs.

CLPOL: Current-Limit Polarity for PWM Generator # bit⁽¹⁾
1 = The selected current-limit source is active-low
0 = The selected current-limit source is active-high
CLMOD: Current-Limit Mode Enable bit for PWM Generator # bit
1 = Current-limit function is enabled
0 = Current-limit function is disabled
Note 1: These bits should be changed only when PTEN = 0. Changing the clock selection during operation will
yield unpredictable results.
2: When Independent Fault mode is enabled (IFLTMOD = 1), and Fault 1 is used for Current-Limit mode
(CLSRC<4:0> = b0000), 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.
3: When Independent Fault mode is enabled (IFLTMOD = 1) and Fault 1 is used for Fault mode
(FLTSRC<4:0> = b0000), 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.
