14.0
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:
• 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

MOTOR CONTROL PWM
MODULE
• Single Pulse Generation mode
• Interrupt support for asymmetrical updates in
• Output override control for Electrically
• ‘Special Event’ comparator for scheduling other
• FLTA pins to optionally drive each of the PWM
This module contains 3 duty cycle generators, num-
bered 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.
A simplified block diagram of the Motor Control PWM
modules is shown in Figure 14-1.
The PWM module allows several modes of operation
which are beneficial for specific power control
applications.
