AWR1843AOP: Interrupt capable pins?

Part Number: AWR1843AOP

Tool/software:

I received a reply from TI supplier that all GPIOs support all interrupt inputs, but after checking with internal software engineer, I found out that not all GPIOs support interrupt function, and only the following GPIOs support interrupts. Is this a misunderstanding?

Please guide me to a gpio that supports interrupts.

  • Hello Kim,

    If you look at the register and the table and map it to the data sheet you will find that from all the GPIO should be programmable to interrupt.
    This is all information from the TRM.

  • Currently, I am using SPI B to communicate by splitting 2 slaves.
    (CS: Assigned to D3, B2)
    G3 port: SPI_MISO is used.
    CS: When both D3 and B2 are High Active,
    Is it possible to change the setting of G3 port from MISO function to interrupt input?
    If possible, please provide technical support.

  • Hello Kim,

    You can use the GIO examples in the SDK: C:\ti\\mmwave_sdk_03_06_00_00-LTS\packages\ti\drivers\gpio\test\xwr18xx
    You can change the functionality based on the data sheet:

    and then use it to select the right mode.

    I would suggest you to first run the example application for Gpio with the above pin of GPIO22 and then check whether you are able to drive it high and low and generates interrupt.

    After that you can integrate in your final application.
