When A Master Rebuilds A Burst Which Has Been Terminated Early Are There Any Limitations On How It Rebuilds The Burst? |
|
Answer» The only limitation is that the master uses legal burst combinations to REBUILD the burst. For example, if a master was performing an 8 beat burst, but had only COMPLETED 3 transfers before losing control of the bus, then the remaining 5 transfers could be performed EITHER by using a 1 beat SINGLE burst followed by a 4 beat INCR burst, or it could be performed using a 5 beat undefined length INCR burst. For simplicity it is recommended that masters use INCR bursts to rebuild the remaining transfers. The only limitation is that the master uses legal burst combinations to rebuild the burst.
