Hi,

thank you for your reply but this link is not helpful for my question, in this vedio it directly linked to another module and didnt show the link information.

I'm trying to understand is what is the meaning and function of the loanIO_in and loanIO_out, the document said it is in to HPS and out of HPS.

Like I asked in the UART problem, which version is correct?

If you can give me a certain answer for my last question, I can understand the issue.

Reguards.
