14.2.3.3.2 Time-Base Counter Synchronization
A time-base synchronization scheme connects all of the ePWM modules on a device. Each ePWM
module has a synchronization input (EPWMxSYNCI) and a synchronization output (EPWMxSYNCO). The
input synchronization for the first instance (ePWM1) comes from an external pin. The possible
synchronization connections for the remaining ePWM modules is shown in Figure 14-7.
