6.4.3.1 Example: System bus master is master value master
Generally, the system bus master is the master value master. All other system bus nodes
(sla
ves) receive an idencal master value from the master.
Fig. 29: Example 1 - System bus master is master value master
M System bus master
VM Virtual master
S Slave
In the system bus master, the exisng virtual master is used to generate master values. These
generated master values constute the master values for all system nodes so all parameters of
the system bus matrix are set to "Master" (default seng).
