How long is the bus stalled for program Flash block erase and program operations?

I would like to write to and erase Flash sectors while running an application from Flash in sectors not being modified.  Reading about IAP it appears the flash bus gets stalled when a flash erase or write is in progress.  However, I could not find how long the bus is stalled.

Ideally I would like to continue with a fully functional application while modifying flash but am concerned timing may be impacted while doing so.
