15.0
This module simplifies the task of generating multiple,
synchronized Pulse-Width Modulated (PWM) outputs.
In particular, the following power and motion control
applications are supported by the PWM module:
• 3-Phase AC Induction Motor
• Switched Reluctance (SR) Motor
• Brushless DC (BLDC) Motor
• Uninterruptible Power Supply (UPS)
The PWM module has the following features:
• 8 PWM I/O pins with 4 duty cycle generators
• Up to 16-bit resolution
• ‘On-the-fly’ PWM frequency changes
• Edge and Center-Aligned Output modes
• Single Pulse Generation mode
• Interrupt support for asymmetrical updates in
• Output override control for Electrically
• ‘Special Event’ comparator for scheduling other
• Fault pins to optionally drive each of the PWM
• Duty cycle updates are configurable to be

This data sheet summarizes the features
of this group of dsPIC33F devices. It is not
intended to be a comprehensive reference
source. To complement the information in
this data sheet, refer to the “dsPIC30F
Family Reference Manual” (DS70046).
Preliminary
This module contains 4 duty cycle generators,
numbered 1 through 4. The module has eight PWM
output pins, numbered PWM1H/PWM1L through
PWM4H/PWM4L. The eight I/O pins are grouped into
high/low numbered pairs, denoted by the suffix H or L,
respectively. For complementary loads, the low PWM
pins are always the complement of the corresponding
high I/O pin.
The PWM module allows several modes of operation
which are beneficial for specific power control
applications.
