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 PENH: PWMH Output Pin Ownership bit
1 = PWM module controls the PWMxH pin
0 = GPIO module controls the PWMxH pin
bit 14 PENL: PWML Output Pin Ownership bit
1 = PWM module controls the PWMxL pin
0 = GPIO module controls the PWMxL pin
bit 13 POLH: PWMH Output Pin Polarity bit
1 = PWMxH pin is active-low
0 = PWMxH pin is active-high
bit 12 POLL: PWML Output Pin Polarity bit
1 = PWMxL pin is active-low
0 = PWMxL pin is active-high
bit 11-10 PMOD<1:0>: PWM # I/O Pin Mode bits
(1)
11 = PWM I/O pin pair is in the True Independent Output mode
10 = PWM I/O pin pair is in the Push-Pull Output mode
01 = PWM I/O pin pair is in the Redundant Output mode
00 = PWM I/O pin pair is in the Complementary Output mode
bit 9 OVRENH: Override Enable for PWMxH Pin bit
1 = OVRDAT<1> provides data for output on the PWMxH pin
0 = PWM generator provides data for the PWMxH pin
bit 8 OVRENL: Override Enable for PWMxL Pin bit
1 = OVRDAT<0> provides data for output on the PWMxL pin
0 = PWM generator provides data for the PWMxL pin
bit 7-6 OVRDAT<1:0>: Data for PWMxH and PWMxL Pins if Override is Enabled bits
If OVERENH = 1, then OVRDAT<1> provides data for PWMxH
If OVERENL = 1, then OVRDAT<0> provides data for PWMxL
bit 5-4 FLTDAT<1:0>: State for PWMxH and PWMxL Pins if FLTMOD is Enabled bits
(2)
FCLCONx<IFLTMOD> = 0: Normal Fault mode:
If Fault is active, then FLTDAT<1> provides the state for PWMxH
If Fault is active, then FLTDAT<0> provides the state for PWMxL
FCLCONx<IFLTMOD> =
1: Independent Fault mode:
If current-limit is active, then FLTDAT<1> provides data for PWMxH
If Fault is active, then FLTDAT<0> provides the state for PWMxL
Note 1: These bits should be changed only when PTEN = 0. Changing the clock selection during operation will
yield unpredictable results.
2: The state represents the active/inactive state of the PWM module depending on the POLH and POLL bit
settings.
