Part Number:TMS320F28375D
Hello, I am using TMS320F28375D_ZWT_337 in my design.
I have an issue which I can’t figure out why or what is happening:
When I set GPIO107 through XBAR to drive XINT2 or XINT5 for interrupt operation, it worked OK for what it set for.
However, with no reason or any connection, the EMIF1 operation suddenly became 10 times slower.
This is only happens on GPIO107. If I switch to use GPIO108/GPIO109/GPIO6, there was no influence on EMIF1 at all.
Wonder if you can give me an explanation.
