5.9.2.1 Control Peripherals Synchronization
The ePWM and eCAP synchronization chain on the device provides flexibility in partitioning the ePWM
and eCAP modules between CPU1 and CPU2 and allows localized synchronization within the modules
belonging to the same CPU. Like the other peripherals, the partitioning of the ePWM and eCAP modules
needs to be done using the CPUSELx registers. Figure 5-48 shows the synchronization chain architecture.
