tps65982: Difference between Full and Reduced projects when IC is programmed

WST
Expert 1015 points
Part Number: TPS65982

I notice that the Reduced and Full projects for a given setup show a different value for the 'Application Configuration Used' number out of the 0x400 space. The reduced also don't allow selection of multiple configuration sets.
What happens to the not displayed registers in the reduced image? Are they left at some default value when the TPS65982 is loaded from the image that is downloaded to the SPI part? I can't find this described anywhere in the documentation for the App Config tool. The word 'reduced' isn't in the .pdf instructions.
I could do some experiments with loading a configuration and then reading the various registers, but I am assuming there is a better answer.

Do the 'missing' registers in the reduced templates just load with a default value?

    Hello,

    The registers on the reduced template are the same as the registers on the full template. The only difference is what is visible on the App Config tool GUI. The GUI simply doesn't show you the full range of register options when using the reduced template.

    Thanks

    So, if I make a binary file with the reduced template, what is programmed into the registers that aren't shown? Do they hold default values?

    Hi,

    The values that are stored in the registers that are not shown are programmed to be 'common sense' or 'average' values - for example if OCP is 5, 10 or 15% the value that is chosen for the register is 10% because it is the middle. So, they could be considered as 'default' values but really they are values that just make the most sense for that specific register.

    note: The reduced version of course doesnt have all the features however you could import a reduced template into a full template in order to see view and modify the registers that are not included in the reduced by itself.

    Thanks
