The Enhanced Pulse Width Modulator (ePWM) module described in this reference guide is a Type 0
ePWM. See the TMS320x28xx, 28xxx DSP Peripheral Reference Guide (
) for a list of all
devices with a ePWM module of the same type, to determine the differences between the types, and for a
list of device-specific differences within a type. This reference guide includes an overview of the module
and information about each of its sub-modules:
•
Time-Base Module
•
Counter Compare Module
•
Action Qualifier Module
•
Dead-Band Generator Module
•
PWM Chopper (PC) Module
•
Trip Zone Module
•
Event Trigger Module
