MPC5500 Family Memory Map
This section describes the MPC5500 family memory map. All addresses in the device, including those that
are reserved, are identified in the tables. The addresses represent the physical addresses assigned to each
module. Logical addresses are translated by the MMU into physical addresses.
Reserved register bits are allocated for future products and have a default value of zero. When writing to
a register, the reserved bits default values must be written as well. Most device features are activated by
writing a non-zero value to them.
Reserved memory is allocated for future products, therefore do not write to memory segments that are
designated as reserved.
Under software control of the MMU, the logical addresses allocated to modules can be changed on a
minimum of a 4 KB boundary. Peripheral modules may be redundantly mapped. You must use the MMU
to prevent corruption.
shows a detailed list of the device memory map.
