Hi Allison, Yes, after I set it to "immediate load", there is no case of a high level at the same time. This is because in TBPRD shadow loading, TBPRD = 0, TBCTR = 0, for EPWMA, EPWM_AQ_OUTPUT_HIGH_ZERO is satisfied, for EPWMB, Yes, EPWM_AQ_OUTPUT_HIGH_PERIOD is satisfied, so both output high levels, am I correct? If yes, I would like to confirm two questions: 1. For EPWMB, is the priority of TBCTR = ZERO and TBCTR = TBPRD higher than that of the latter? I did not see the introduction of the priority of both in UP-DOWN mode in the technical manual. 2. After TBCLKSYNC was enabled, I adjusted it to shadow loading, and the entire waveform was lost.
