Address Map Support
The PPC405CR incorporates two simple and 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 (DCR). This address map is accessed by software running on the PPC405CR
processor through the use of MTDCR and MFDCR commands.

Notes:
1. The Local Memory/Peripheral area of the memory map can be configured for SDRAM, ROM or Peripherals.
2. The Boot ROM and Expansion ROM area of the memory map are intended for use by ROM or Flash-type devices. While locating
volatile SDRAM and SRAM in this region is supported by the controller it is not recommended that these regions be used for this
purpose.
