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.

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.
