A dummy master is necessary in any system which has a slave that can GIVE SPLIT transfer responses. The dummy master is required so that something can be granted the bus if all the other masters have received a SPLIT RESPONSE.

No LOGIC is required for the dummy master and it can be implemented by SIMPLY tying off the inputs to the master address/control multiplexer for the dummy master position. The requirements for a dummy master are that HTRANS is driven to IDLE, GLOCK is driven low, and all other master outputs are driven to legal values.
