/2 PWM edge
CY
resolution
• Two output pins (pair) for each PWM generator
• Complementary or independent operation for
each output pin pair
• Hardware dead-time generators for
Complementary mode
• Output pin polarity defined by nonvolatile device
configuration bits
• Multiple output modes:
- Edge-Aligned mode
- Center-Aligned mode
- Center-Aligned mode with double updates
- Single Event mode
• Manual override register for PWM output pins
• Hardware Fault input pins with programmable
function
• Trigger for synchronizing A/D samples and
conversions to PWM timing
• Each output pin associated with the PWM can be
individually enabled

8.3.1
PWM TIME BASE
The PWM time base is provided by a 15-bit timer with
a prescaler and postscaler. The PWM time base can be
configured for four different modes of operation:
• Free-Running mode
• Single-Shot mode
• Continuous Up/Down Count mode
• Continuous Up/Down Count mode with interrupts
for double updates
The Up/Down Counting modes support center-aligned
PWM generation. The Single-Shot mode allows the
PWM module to support pulse control of certain
Electronically Commutated Motors (ECMs).
Table 8-1 lists the frequencies and resolutions that can
be attained as a function of the dsPIC33F device
instruction cycle frequency.
