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 PWMxH pin
0 = GPIO module controls PWMxH pin
bit 14 PENL: PWML Output Pin Ownership bit
1 = PWM module controls PWMxL pin
0 = GPIO module controls 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 PWMxH pin
0 = PWM generator provides data for PWMxH pin
bit 8 OVRENL: Override Enable for PWMxL Pin bit
1 = OVRDAT<0> provides data for output on PWMxL pin
0 = PWM generator provides data for 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
(2)
for PWMxH and PWMxL Pins if FLTMOD is Enabled bits
FCLCONx<IFLTMOD> =
0: Normal Fault mode:
If Fault active, then FLTDAT<1> provides state for PWMxH.
If Fault active, then FLTDAT<0> provides state for PWMxL.
FCLCONx<IFLTMOD> =
1: Independent Fault mode:
If current-limit active, then FLTDAT<1> provides data for PWMxH.
If Fault active, then FLTDAT<0> provides 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: State represents the active/inactive state of the PWM module depending on the POLH and POLL bit set-
tings.
