TMS320F28377D: External Reset Delay

Anthony,

The trip zone (TZn) pins have a much faster effect on the PWM pins. Is your key care-about tri-stating the PWM pins as quickly as possible? Could you please provide more information on why you need the time it takes for reset to propagate inside the device? 

We have an external reset signal that can be provided at any time that is mapped to the reset of the processor.  We have some hardware logic to shut down components that the processor is controlling and want to know how long after the reset does the processor really stop.

We just noticed this long delay with the PWM outputs and were surprised they stayed on for so long and wanted to know if there was a spec on how long this delay was.

The TZ inputs may be useful but we would still like to characterize what kind of delay to expect from the XRS.

Is your main concern the PWM pins or the overall operation of the device in general?

We do not have this information at the moment. I have reached out to the Design team to check if they may be able to provide it. It will likely take a few days.

We would like to know the overall operation of the device in general (focusing on the PWMs, SPI, and GPIO). 

Thanks for reaching out to the design team.
