TMS320F28377D: Inquiry about GPIO Input Qualification for SDFM

Other Parts Discussed in Thread: AMC1303M2510

Hi Experts,

We received one Inquiry about SDFM GPIO Input Qualification. According to “14.2 Configuring Device Pins” in F28377D’s  TRM, there is the following description. Customer believes customer is able to use ASYNC mode and 3-sample mode. If customer used other GPIO qualifications (for instance, SYNC), customer is asking what kind of concerns would TI expect. Can I have any advice/comments on this question?

     "For proper SDFM operation, following GPIO input qualification can be used. Other GPIO qualifications are not supported."

I believe customer is just asking it.

Best regards,

Miyazaki
