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.
IFLTMOD: Independent Fault Mode Enable bit
1 = Independent Fault mode: Current-limit input maps FLTDAT<1> to PWMxH output and Fault input
0 = Normal Fault mode: Current-Limit mode maps CLDAT<1:0> bits to the PWMxH and PWMxL
CLSRC<4:0>: Current-Limit Control Signal Source Select bits for PWM Generator #
These bits also specify the source for the dead-time compensation input signal, DTCMPx.
