Address Maps
The PPC440EP incorporates two address maps. The first is a fixed processor System Memory Address Map. This
address map defines the possible contents of various address regions which the processor can access. The
second is the DCR Address Map for Device Configuration Registers (DCRs). The DCRs are accessed by software
running on the PPC440EP processor through the use of mtdcr and mfdcr instructions.
