Memory Map
Each of the processors on the ADS board uses its own memory map.
3.1 MPC8560 Host Mapping for the MSC8144ADS
The MPC8560 Memory Controller governs all access to the processor memory slaves.
Consequently, the memory map may be reprogrammed according to specific user needs. After
performing a Hard Reset sequence, the debug host may initialize the memory controller via the
JTAG/COP connector to allow additional access to bus addressable peripherals. The SDRAM
DDR responds to all types of memory access including program, data, and direct memory
accesses (DMA).
