EVM430-FR6047: EVM430-FR6047: What is the difference between "AUTO mode" and "Ultra low power mode".

Hello,

I am interested in knowing the difference between "AUTO mode" and "Ultra low power mode" regarding the measurement control (apart from an additional "holdoff time" in ultra low power mode.)

Regards,

Mr. Jadhav

    Hello Mr. Jadhav,

    Can you clarify what you are referring to? If you can point to some documentation or code example, that would be helpful.

    If you are referring to the auto switching between UPS and DNS vs. ultra low power configuration, the auto mode is using the USS module in the chip to automatically switch between UPS and DNS and will be in LPM0 in between. In the ultra low power configuration, the switching of UPS and DNS is software controlled and is going to LPM3 between states. Let me know if this is what you are referring to or not. Thanks!

    Hello Eddie,

    I am referring to the data acquisition sequence modes. AUTO mode, REGISTER mode and ULTRA low power mode as mentioned below.

    Yes! what you mentioned is what I understood from the above description as well regarding the switching control.

    But I see that the Auto mode and Ultra low power mode are same except that the in ultra low power mode we can introduce an additional "holdoff delay" (This is the extended power sequence? ) of max 300us for less power consumption than in AUTO mode.

    So to summarize:

    AUTO mode: ASQ control

    REGISTER mode: Software control

    ULTRA low-power mode: ASQ control + "holdoff delay" (Extended power sequence ).

    is this correct? or are there any additional features in Ultra low power mode which I am missing?

    Regards,

    Jadhav

    Jadhav,

    Your understanding is correct regarding the modes. By default, in the demo code, we are using the ultra low power mode to show lowest power performance.
