PPC405EZ – PowerPC 405EZ Embedded Processor
6
AMCC Proprietary
Revision 1.27 - August 22, 2007
Preliminary Data Sheet
Address Maps
The PPC405EZ incorporates two address maps. The first address map defines the possible use of addressable
memory regions that the processor can access. The second address map defines Device Configuration Register
(DCR) addresses (numbers). The DCRs are accessed by software running on the PPC405EZ processor through
the use of mtdcr and mfdcr instructions.
