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 15-8 FBOVxH<4:1>:FBOVxL<4:1>: Fault Input B PWM Override Value bits
1 = The PWM output pin is driven active on an external Fault input event
0 = The PWM output pin is driven inactive on an external Fault input event
bit 7 FLTBM: Fault B Mode bit
1 = The Fault B input pin functions in the Cycle-by-Cycle mode
0 = The Fault B input pin latches all control pins to the states programmed in FLTBCON<15:8>
bit 6-4 Unimplemented: Read as ‘0’
bit 3 FBEN4: Fault Input B Enable bit
(1)
1 = PWM4H/PWM4L pin pair is controlled by Fault Input B
0 = PWM4H/PWM4L pin pair is not controlled by Fault Input B
bit 2 FBEN3: Fault Input B Enable bit
(1)
1 = PWM3H/PWM3L pin pair is controlled by Fault Input B
0 = PWM3H/PWM3L pin pair is not controlled by Fault Input B
bit 1 FBEN2: Fault Input B Enable bit
(1)
1 = PWM2H/PWM2L pin pair is controlled by Fault Input B
0 = PWM2H/PWM2L pin pair is not controlled by Fault Input B
bit 0 FBEN1: Fault Input B Enable bit
(1)
1 = PWM1H/PWM1L pin pair is controlled by Fault Input B
0 = PWM1H/PWM1L pin pair is not controlled by Fault Input B
Note 1: Fault A pin has priority over Fault B pin, if enabled.
