How long does the DONE pin take to go low after PROG_B goes low in a Spartan 3A?

How long does the DONE pin take to go low after PROG_B goes low in a Spartan 3A?  If possible could you point me to where you found the information?

 

Thanks,

Dale

This parameter isn't specified as it isn't a critical number with respect to the configuration sequence as DONE low is not a useful state condition.  

 

The timing between PROG_B and INIT_B is specified in the Spartan-3A Datasheet DS529.
