Memory Map
The following table shows the memory map in the i.MX23 as seen by the processor. Any blank entries
indicate that nothing is mapped at that address. No accesses should be made to these addresses since the
results are indeterminate. The Decode Block column indicates the decode group to which each peripheral
belongs. Most peripherals reside on the APBH or APBX peripheral busses.
