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 (SPRU566 ) 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
