What is the difference between Oversampling Continued vs Resumed mode in ADC?

What is the difference between Oversampling Continued vs Resumed mode?
I understand that in Oversampling Continued without resetting the accumulator in between individual samples for that channel. Resumed Mode resets it.

I don't understand the implication on the final output for Scan Conversion Multi Channel Oversampled ADC. I have argued with ChatGPT for soo long. I tried looking for something in manuals but..

Edit: After arguing for soo long again ChatGPT says, " channel mixing can occur in Oversampling Continued Mode if the accumulator is not reset between channels, leading to incorrect results due to leftover data from previous channels. This is the key limitation of Continued Mode when dealing with multiple channels in scan conversion"

Google search returns no results for "Oversampling Continued vs Resumed mode". This post may help.

    Don't talk with AI, read RM:

    •In continued mode, the accumulation restarts from the last valid data (prior to the
    conversion abort request due to the injected trigger). This ensures that oversampling
    will be completed whatever the injection frequency (providing at least one regular
    conversion can be completed between triggers);
    •In resumed mode, the accumulation restarts from 0 (previous conversions results are
    ignored). This mode allows to guarantee that all data used for oversampling were
    converted back-to-back within a single timeslot. Care must be taken to have a injection
    trigger period above the oversampling period length. If this condition is not respected,

    I havent looked much into this, but i found the examples quite comprehensive in the manual of the G431.
