For slaves that are in the HN-I memory region, some system designs might provide access to those slaves through a different path from the HN-I. In these circumstances, you must program the HN-I registers so that the Point-of-Serialization (PoS) is set correctly.
The following figure shows an example system configuration where an HN-I slave is accessible to other AXI masters.
The required programming is:
That is, set:
