1 Introduction

Before migrating an EPWM application to MCPWM, there are high-level feature differences between the two modules to determine whether migration between the two modules is feasible for an existing application. Once this evaluation is complete, users can begin migrating a EPWM code to MCPWM. This document highlights differences for both register and driverlib-based programming. Differences between EPWM and MCPWM are divided between the following submodules:

  • Time-based submodule
  • Counter-compare submodule
  • Action qualifier submodule
  • Deadband submodule
  • Trip-zone submodule
  • Event trigger submodule
  • PWM X-BAR
