Hi guys...

I am trouble again..... :wacko:

My question is :

If slave 0 gives split error to two masters say master 0 and master 1...
Now slave can generate Hsplitx for both masters at same time??
Or slave can generate Hsplitx for only one master at a time....???

Please reply ASAP......
Thanks in advance....

    By asserting HSPLIT bits, the slave is not talking to two masters at the same time, in fact it is not talking to any master.

    HSPLIT tells the arbiter that one (or more) masters can now be re-enabled in the arbitration scheme again.

    The arbiter decides which master should be next granted, and when appropriate, the previously SPLIT master(s) will become granted.

    Obviously only one master will be granted at a time.

    HSPLIT tells the arbiter when masters can be re-enabled in the arbitration scheme, not that they must be immediately granted. I think this is what is confusing you.
