TMS320F28379D: How to connect the Post Processing Block Trip HI & LO EVENT outputs connected to EPWM Trip Input. Cannot find a path.

David Petryk

Part Number: TMS320F28379D

I am wanting to use the Trip HI trip LO outputs from the Post Processing Block to a trip input on a EPWM to shut it down on an over current event.

Figure 14-17 shown it should be able to do that but I cannot find a register that makes it happen. Trip 7, 8, 9, 10 are the trips I want to use.

I must be missing something. Is the "EPWM X-BAR" different from the "X-BAR".

Anyway I cant find a path to make this connection.

Thanks, Dave..

Hi,

You have use ADCEVTx for that purpost.
Please check Table 11-50. ADCEVTSEL Register Field Descriptions in the Analog-to-Digital Converter (ADC) chapter.

Thanks for your reply.

What document are you referring to?

I was looking in "SPRUHM8H–December 2013–Revised January 2019" and I found these tables & figures

Neither have anything to do with ADCEVTx .

Table 11-50 & Figure 11-50.
