The EPWMSYNCPER signal comes from the Time-Base submodule of the EPWM. For a detailed description of how this signal is generated, refer to Enhanced Pulse Width Modulator (ePWM).
When DACCTL.LOADMODE = 1, the selected EPWMSYNCPER signal loads a new DACVALA value. The EPWMSYNCPER signal operates as a high logic-level trigger load. If TBCTR and TBPRD of the EPWM are both 0, EPWMSYNCPER is held at a high level and DACVALA is immediately loaded from DACVALS irrespective of the value of DACCTL.LOADMODE. To control the timing of this initial EPWMSYNCPER triggered load the EPWM and EPWMSYNCPER output must be configured prior to setting DACCTL.LOADMODE = 1.
