TMS320F28034: AQCSFRC shadow mode effect timing.

Tool/software:

Hi experts,

My customer is using two AQ, AQCSFRC (shadow to active when CTR=0) set high and CTR=0 set low.

These two AQ event occurs at the same time and the TRM says:

"The general rule is events occurring later in time have a higher priority and software forced events always have the highest priority"

does it mean that the two events happens one after another? Customer is observing a spike at CTR=0, would it results form a CTR=0 set low right after software set high?

Regards,

Hang.

    Hi Hang,

    The continuous software force always takes priority regardless of whether it happens before or after other action qualifier events. You may observe a spike in the output if an action qualifier event happens immediately before a continuous software force event.

    To clarify, you're saying the TBCTR=0 event sets the output low and the continuous software force sets the output high? Are there any other action qualifier events that set the output high? Can you provide a screenshot of the spike?

    Thank you,

    Luke
