    Hi AnilKumar,

    Thank you very much!!!

    I have read the post you provided for me. however, I think it doesn't  solve my problem, because now I think the pin GPIO47 on DM368 doesn't support to be configured to output interrupt signal, as there is no interrupt register for GPIO47 in bank 2 described in "TMS320DM36x Digital Media System-on-Chip (DMSoC) General-Purpose Input/Output (GPIO) User's Guide" P18, is it right???

    Thanks for your attention again!!!

    Hi Bruce Lee,

    Yes, what you had oberved is correct. Interrupt sources are available only 0-15 and [106:104] gpio lines.
