405GPr – Power PC 405GPr Embedded Processor

AMCC

Revision 2.04 – September 7, 2007

Data Sheet

Address Map Support

The PPC405GPr incorporates two simple and separate address maps. The first address map defines the possible

use of address regions that the processor can access. The second address map is for Device Configuration

Registers (DCRs). The DCRs are accessed by software running on the PPC405GPr processor through the use of

mtdcr and mfdcr instructions.

Notes:

1. When 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.
