TMS320F28388D: CLA interrupt using EPWM1

inno

Part Number: TMS320F28388D

hello all,

I used the Epwm1 as a interrupt source for the CLA core.

how can I set the interrupt to start at a certain epwm1 comparator value? (TBCTR register) ?

now im cant tell if the interrupt happens at the zero or period or some comparator of the epwm1 - i set my EPWM1 to zero.

i tried to read the TBCTR value in the CLA core and received changing values..

thanks

Hi,

Can you let me know how the EPWM is being configured for generating interrupt ?

Thanks,

You can use CMPC or CMPD registers for EPWM1 to generate interrupts at the specific comparator value. Event selection for interrupt generation can be done using the ETSEL register.

Thanks,
