UVM driver communication to sequencer

In reply to syed taahir ahmed:

Hi
I am having a doubt in the driver communicating the response back to sequencer through the seq_item_port.item_done (rsp) but how does this rsp is implemented in sequence body task,can anybody explain with one example?
I have checked the Cookbook Driver/Sequence API but things are not clear
.
Thanks
Taahir

Can anybody explain how set_item_done(rsp) is implemented in Sequence?
