6 / 80 page ![]() PowerPC 440SPe Embedded Processor 6 AMCC Proprietary Revision 1.23 - Sept 21, 2006 Preliminary Data Sheet Address Maps The PPC440SPe incorporates two address maps. The first is a fixed processor system memory address map. This address map defines the possible contents of various processor accessible address regions. The second address map identifies the system Device Configuration Registers (DCRs). DCRs are accessed by software running on the PPC440SPe processor through the use of mtdcr and mfdcr instructions.
