TMS320F28379D: how to set an interrupt from CMPSS block

Giovanni Bassi18

Part Number: TMS320F28379D

Hi.

I want to trigger an interrupt when a CMPSS output trips over a ~80KHz analog signal.

The CMPSS section of the manual says that CMPSS can be connected only to ePWM XBAR or OUTPUT X-BAR.

I would like to know if there is a more direct way than this:

CMPSSTRIPx >>> Output X-BAR >>> GPIOMux >>> Input X-BAR >>> CPUx.XINTX.Control >>> CPUx ePIE >>> INTx

My obiective is NOT ePWM protection (I already used ePWM TRIP ZONE submodule for this) but measuring. So, I need interrupts.

Best regards,

Giovanni

Hi Giovanni,

The CMPSS itself does not have interrupt generation capability so the two ways you outlined are the only ways.

Thank you, Frank.

I will create that chain, then.

Best regards,

Giovanni.
