TMS320F280049C: ePWM Syncing

Unfortunately from my understanding of your question, we don't have this built into the hardware but as far as software you can easily avoid having duplicate code when using both drivelib and bitfields.

The places in your code where you need to duplicate the configurations for both EPWM1 and EPWM2, you can write functions that look like this:

void initEPWM(uint32_t epwm_base)
{
    //
    // Set-up TBCLK
    //
    EPWM_setTimeBasePeriod(epwm_base, EPWM1_TIMER_TBPRD);
    EPWM_setPhaseShift(epwm_base, 0U);
    EPWM_setTimeBaseCounter(epwm_base, 0U);
...
}

or for bitfields you can do:

volatile struct EPWM_REGS *ePWM[PWM_CH] =
{  &EPwm1Regs, &EPwm1Regs, &EPwm2Regs, &EPwm3Regs, &EPwm4Regs, &EPwm5Regs,
   &EPwm6Regs, &EPwm7Regs, &EPwm8Regs};

void InitEPwm()
{
   for(j=1; j<PWM_CH; j++)
    {
        (*ePWM[j]).TBCTL.bit.PRDLD = TB_SHADOW;  // set Shadow load
        (*ePWM[j]).TBPRD = period;               // PWM frequency = 1/(2*TBPRD)
        (*ePWM[j]).CMPA.bit.CMPA = period / 2;   // set duty 50% initially
        (*ePWM[j]).CMPA.bit.CMPAHR = (1 << 8);   // initialize HRPWM extension
        (*ePWM[j]).CMPB.bit.CMPB = period / 2;   // set duty 50% initially
        (*ePWM[j]).CMPB.all |= 1;
        (*ePWM[j]).TBPHS.all = 0;
        (*ePWM[j]).TBCTR = 0;
...
...
}
