PPC405EX – PowerPC 405EX Embedded Processor
Address Maps
The PPC405EX 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 PPC405EX processor through
the use of mtdcr and mfdcr instructions.

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.
3. PCI Express can use PLB address range 0x1 0000 0000 to 0xF FFFF FFFF even though the CPU can not access it.
