Active Configuration Rom and Bus_Manager_ID reads
If Configuration-Rom information of some node or the Bus_Manager_ID register value is needed, the
Analyzer will read it actively. It will only use quadlet read transactions.
If the ‘node display options’ that are retrieved from the Bus_Info_Block are all disabled and if the ‘Bus and
node information’ button is not pressed, the Analyzer will not generate any active transactions.
If one or more ‘node display options’ are enabled that need to be retrieved from the Bus_Info_Block or if
the ‘Bus and node information’ button is pressed and a node is selected, then the Configuration Rom of
one or more nodes will be read when needed.
If the ‘Bus and node information’ button is pressed, the Bus_Manager_ID register will be read too when
needed.
