SCAN15MB200: SI+/− SO+/− if support the 1149.1 for single-end test

Part Number: SCAN15MB200

hi sir

 

1
We've always used the 1149.1 JTAG port on the SCAN15MB200 to port SI+/- and SO+/- DIFF pairs for 1149.6
boundary scan testing, and this has worked fine.
2.
Now, we requires that SI+/- and SO+/- DIFF pair 1 also be ported to 1149.1.can do it?

3. 
I checked the BSDL for Scan15MB200, and it appears feasible. However,
in actual testing, we encountered some issues; the SI+/- and SO+/- DIFF pairs are not working correctly in version 1149.1.
This requires TI's assistance for confirmation. Therefore, we are currently unable to test the following issues:
thanks
