"Hello, in the tidm_1000 example, the CLA unit is triggered by the PWM interrupt, but the PWM ISR function code is left as a comment. When this function is used, both the IFR and PIACK bits are cleared, but within the CLA unit, only the PWM IFR bit is cleared with EPWM_clearEventTriggerInterruptFlag(base); . Now, in this usage, why isn't the PIACK bit cleared in the CLA unit with Interrupt_clearACKGroup(pie_group_no); ? In which situations should we clear this bit?" Best Regards, Enes
