4.6. Slave to master multiplexor

The slave to master multiplexor is used to connect the read data and response signals of the system bus slaves to the bus masters, using the current decoder HSELx outputs to select the bus slave outputs to use. Figure 4.22 shows the slave to master multiplexor module.

Slave to master multiplexor module interface diagram

This module has the read data and response outputs of all system bus slaves as its inputs, and has a single set of these signals as its outputs, which are connected to the inputs of all system masters. When slaves are added to the system or removed, the input connections to this module must be altered to account for the changes.
