Internal Memory Map Register (IMMR)
The internal memory map register (IMMR) is a register located within the MPC561/MPC563 special
register space. The IMMR contains identification of a specific device as well as the base for the internal
memory map. Based on the value read from this register, software can deduce availability and location of
any on-chip system resources.
This register can be read by the mfspr instruction. The ISB field can be written by the mtspr instruction.
The PARTNUM and MASKNUM fields are mask programmed and cannot be changed.
