Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15 IFLTMOD: Independent Fault Mode Enable bit
1 = Independent Fault mode is enabled
0 = Independent Fault mode is disabled
bit 14-10 CLSRC<4:0>: Current-Limit Control Signal Source Select for the PWMx Generator # bits

bit 9 CLPOL: Current-Limit Polarity for PWMx Generator # bit
(1)
1 = The selected current-limit source is active-low
0 = The selected current-limit source is active-high
bit 8 CLMOD: Current-Limit Mode Enable for PWMx Generator # bit
1 = Current-Limit mode is enabled
0 = Current-Limit mode is disabled
Note 1: These bits should be changed only when PTEN = 0. Changing the clock selection during operation will
yield unpredictable results.
