This is the second video in the C2000 ePWM video series, which covers type 4 ePWMs. This video details the time-base submodule found within the ePWM module. The time-base submodule serves as the foundation of the ePWM module and is responsible for configuring the period and frequency of the time-base counter. This module also sets the mode of the time-base counter and configures the phase and synchronization of the ePWM. A few examples of relevant calculations will be provided to further develop understanding.
