NPe405H – PowerNP NPe405H Embedded Processor
ADDRESS MAP SUPPORT
The NPe405H incorporates two separate address maps. The first is a fixed processor address map that serves the
PowerPC family of processors. This address map defines the possible contents of various address regions which
the processor can access. The second address map is for Device Configuration Registers (DCRs). The DCRs are
accessed by software running on the NPe405H processor through the use of mtdcr and mfdcr commands.

Notes:
1. When external peripheral bus boot is selected, peripheral bank 0 is automatically configured at reset to the address range listed above.
2. If PCI boot is selected, a PLB-to-PCI mapping is automatically configured at reset to the address range listed above.
3. After the boot process, software may reassign the boot memory regions for other uses.
4. All address ranges not listed above are reserved.
