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.
