Each EPWM module has its own time-base submodule that determines all of the timing events. Built-in synchronization logic allows the time-base of multiple EPWM modules (EPWMx) to work together as a single system. Figure 12-241 illustrates the time-base module's place within the EPWM.
The TB module generates the period (or frequency) of the PWM output waveforms and consists of a 16-bit counter that can be configured for up, down or up and down counting. The time base for the counter is a pre-scaled version of the system clock (FICLK/n) which can be programmed for a pre-scale of 1, that is same as system clock.
