+SRAM Bus Access Partitioning
+****************************
+
+RW612 supports shared access of the SRAM from both the code bus and data bus.
+The bus used to access the SRAM is determined using two separate memory mapped address spaces.
+The application can configure the partitioning of the SRAM access regions by a devicetree overlay.
+For example, below is part of an overlay to change the whole SRAM to be used for data.
+
+.. code-block:: devicetree
