2.2.3.6
If two local access windows overlap, the lower numbered window takes precedence. For instance, if two
windows are set up as shown in
region from 0x0_7FF0_0000 to 0x0_7FFF_FFF, even though the window described in local access
window 2 also encompasses that memory region.
2.2.3.7
Once a local access window is enabled, it should not be modified while any device in the system may be
using the window. Neither should a new window be used until the effect of the write to the window is
visible to all blocks that use the window. This can be guaranteed by completing a read of the last local

Identifies the target interface ID when a transaction hits in the address range defined by this
window. Note that configuration registers and SRAM regions are mapped by the windows defined
by CCSRBAR and L2SRBAR. These mappings supersede local access window mappings, so
configuration registers and SRAM do not appear as a target for local access windows.
