Here's my presentation regarding PSE connection check usage, and 2 alternatives for baseline to address the problem.
The presentation and option1 are same as posted to allfiles. Option2 baseline is updated (see attached) to fix a typo in Page 119 modifications (was "sig_type = invalid * sig_pri != valid * sig_sec != valid", now fixed as "sig_type = invalid + sig_pri != valid + sig_sec != valid").
I recognize there's a lot of ground covered in all these files. While considering the original problem, I recognized an opportunity to make the distinction between connection check and detection while providing a flexible framework for all "connection check/detect sequences" to be compliant, provided they meet the existing timing requirements (tdet, tpon, and inter-function timing "tcc_det"). This is option 1.
If you have any questions about my approach, if you have concerns about support for one or another existing "CC_DET_SEQ", or if you have found any errors, please feel free to reach out.
Thanks for your consideration.
