bit 2

FLTPOL: Fault Polarity bit for PWM Generator #(1)

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 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.

3: When Independent Fault mode is enabled (IFLTMOD = 1) and Fault 1 is used for Fault mode

(FLTSRC<4:0> = b0000), 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.
