What caused the early burst termination ?

If it was a non-OKAY response from the slave being accessed, HRESP won't be OKAY.

If it was arbitration logic switching between masters in the middle of a burst, HRESP will be OKAY (unless that transfer coincidentally also had a non-OKAY response).

But in both cases HREADY has to be high before the next transfer (in the current burst, or the next one) can start.
