4.6.2. Function and operation of module

The slave to master multiplexor controls the routing of read data and response signals from the system bus slaves to the bus masters. The decoder determines which is the currently selected slave, and the multiplexor is used to connect the outputs of the selected slave to the inputs of the bus masters.

The read data and response signals are switched during the data phase of a transfer, so a registered version of the slave select signals is used.

The default slave inputs are used when no other slaves are selected.
