PPC405EZ – PowerPC 405EZ Embedded Processor
Address Maps
Preliminary Data Sheet
The PPC405EZ incorporates two address maps. The first address map defines the possible use of addressable
memory regions that the processor can access. The second address map defines Device Configuration Register
(DCR) addresses (numbers). The DCRs are accessed by software running on the PPC405EZ processor through
the use of mtdcr and mfdcr instructions.

Boot Address Range
Notes:
1. If peripheral bus boot is selected, peripheral bank 0 is automatically configured at reset to the address range listed above.
2. After the boot process, software may reassign the boot memory regions for other uses.
