37.3.2 PWM[n]_X - Auxiliary PWM Output signal
These pins are the auxiliary output pins of the PWM channels. They can be independent
PWM signals. When not needed as an output, they can be used as inputs to the input
capture circuitry or used to detect the polarity of the current flowing through the
complementary circuit at deadtime correction.
37.3.3 FAULT[n] - Fault Inputs
These are input pins for disabling selected PWM outputs.
37.3.4 PWM[n]_EXT_SYNC - External Synchronization Signal
These input signals allow a source external to the PWM to initialize the PWM counter. In
this manner, the PWM can be synchronized to external circuitry.
37.3.5 EXT_FORCE - External Output Force Signal
This input signal allows a source external to the PWM to force an update of the PWM
outputs. In this manner, the PWM can be synchronized to external circuitry.
37.3.6 PWM[n]_EXTA and PWM[n]_EXTB - Alternate PWM
Control Signals
These pins allow an alternate source to control the PWM_A and PWM_B outputs.
Typically, either the PWM_EXTA or PWM_EXTB input (depending on the state of
MCTRL[IPOL]) is used for the generation of a complementary pair. Typical control
signals include ADC conversion high/low limits, TMR outputs, GPIO inputs, and
comparator outputs.
37.3.7 PWM[n]_OUT_TRIG0 and PWM[n]_OUT_TRIG1 - Output
Triggers
These outputs allow the PWM submodules to control timing of ADC conversions. See
the description of the Output Trigger Control Register for information about how to
enable these outputs and how the compare registers match up to the output triggers.
