Note 1:
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 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.
