Each purge request is sent by driver after master core is powered up and unresetted but before it is unstalled. On unstall, ROM begins processing the request and initializing environment for FW load. Host should await ROM's ack before moving forward. Without doing so, ROM init poll may start too early and false timeouts can occur.
