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:
• Three-Phase AC Induction Motor
• Switched Reluctance (SR) Motor
• Brushless DC (BLDC) Motor
• Uninterruptible Power Supply (UPS)
The PWM module has the following features:
• 6 PWM I/O pins with 3 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
This module contains 3 duty cycle generators,
numbered 1 through 3. The module has 6 PWM output
pins, numbered PWM1H/PWM1L through PWM3H/
PWM3L. The six 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.
