TMS320F28335 XINTF Pin Configuration

Other Parts Discussed in Thread: TMS320F28335

Hi all,

I need to use a XINTF 16-bit interface on TMS320F28335.

Can I configure the unused data lines XD[31:16] for other purposes (such as GPIO or SCI)?

Thanks.

    Hi Luca,

    Yup, why not. Please refer the F28335 datasheet for muxing details. You can refer xint and sci peripheral details too for more info.

    Regards,

    Gautam

    Hi Luca,

    I have used the XINTF16 on TMS320F28335. At the same time, I have used the SCI port (Gpio 62,63) and the rest of GPIO without any problem. 

    Only you have to know that lines XA[0..19] always are used for the address. If you want to used those pins with other purpose you will need a system to determinate if the value is address or the other purpose.

    good luck,

    Thanks for the answer,

    I will configure the XINTF in 16-bit mode using SCI and other peripherals on the unused XD pins!
