CTTBLLD over another table

[ERokc]

I need to reload a preset table before the existing one finishes. I also need to CTREGWR a new value to the accumulator. I know how to do each I just need to know the order to do it.

Do I need to clear the existing one first then load the new one?

Can I just load over the existing one?

What's a reliable procedure?

Loading a table overwrites the previously loaded table. No need to clear.

A new table doesn't get fully happy until the associated counter has been through a reset. Reset updates the accumulator.

So...load the table, reset the counter, write the accumulator.

I discovered "counter reset to a value".  Can I load the table, toggle $CTRIO_000_C2F1.Reset to get the accumulator set?  If so that would be cleaner.

Is there a preset table reset?  All I need is to start over periodically.

Yes, that will work.

There is no reset for the table, only the counter.
