FLTSRC<4:0>: Fault Control Signal Source Select bits for PWM Generator #

01011 = Reserved
01010 = Comparator 3

00000 = Fault 1

bit 2

FLTPOL: Fault Polarity bit for PWM Generator #

1 = The selected Fault source is active-low
0 = The selected Fault source is active-high

bit 1-0

FLTMOD<1:0>: Fault Mode bits for PWM Generator #
11 = Fault input is disabled
10 = Reserved
01 = The selected Fault source forces PWMxH, PWMxL pins to FLTDAT values (cycle)
00 = The selected Fault source forces PWMxH, PWMxL pins to FLTDAT values (latched condition)

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 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.

3: 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.
