Preliminary
8.3.1
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
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.
