PRODUCTION DATA
When a Fast Power-On Re-Connect device and/or PHY is connected to an IEEE-1394-2008 Beta PHY and it is power cycled/reset the IEEE-1394-2008 Beta PHY port will go to the P0:Disconnected state and send non-continuous tones (666 microsecond tones).
When the Fast Power-On Re-Connect capable device and/or PHY comes back online, it doesn’t see continuous tones therefore after the appropriate number of connection tones are observed it sets fastPowerConnect = FALSE and transitions to P11:Untested state.
