CC3220: difference between cc3220 Chips

CC3220: difference between cc3220 Chips

HELLO,

WHY ANTSEL PINS ARE USED IN CC3220 ?

IS ALL PINS ARE PULL UP AND PULL DOWN USING SOFTWARE?

CAN JTAG PINS ARE USED FOR BOTH DEBUG AND SOFTWARE IN CC3220

    Hi Monisha,

    1. The ANTSEL pins are for antenna selection. Are you asking for an explanation on antenna diversity?

    2. Yes, all GPIOs are configurable as pull ups or pull downs in software. Please see the CC3220 datasheet (www.ti.com/.../cc3220.pdf) for a complete list of available GPIOs.
    For details on how to configure the GPIOs, please see the TI Drivers API guide: dev.ti.com/.../
    If you are new to TI Drivers, please check out the SimpleLink Academy TI Drivers labs: dev.ti.com/.../

    3. You can configure the default JTAG pins for other uses in your application code if you are not using the JTAG for debugging. The datasheet specifies other available modes for these pins. If you are using the LaunchPad, you will have to remove the JTAG jumpers (see the CC3220 LaunchPad Hardware User's Guide: www.ti.com/.../swru463).

    Best regards,
    Sarah

    thank you.

    i have doubt that using jtag pin can we program and debug the chip cc3220.or we use any other uart pins for seperate.
    also XDS200 ,can used for both programming and debugging.is it possible or not

    Hi Monisha,

    I see that your other E2E question on the SOP pins was resolved: e2e.ti.com/.../2635916

    Was this the same question as above?

    Best regards,
    Sarah
