5.4.2. Function and operation of module

The peripheral to bridge multiplexor controls the routing of read data from the peripheral bus slaves to the bridge. The bridge determines which is the currently selected slave, and the multiplexor is used to connect the output of the selected slave to the input of the bridge.

The read data is switched for the duration of an APB transfer, when the PSELx signal is valid.

A default value of zero is used when no slaves are selected.
