System Memory
Following is the default memory map for this board as configured by the Debug Monitor located
in the external flash bank. The internal memory space of the MPC566 is detailed further in the
MPC565-6 Users Manual. Chip Selects 0-3 can be changed by user software to map the external
memory in different locations but the chip select configuration such as wait states and transfer
acknowledge for each memory type should be maintained.
Possible Chip Select usage:
Synchronous SRAM Memory Bank CS0 or CS1 default CS1, MAP SW. 1,2
Synchronous FLASH Memory Bank CS0 or CS2 default CS0, MAP SW. 3,4
10/100T / LCD Port CS3 default CS3, MAP SW. 6,7
MPC566 Internal Flash N/A MAP_SW. 8, may effect mem-
ory map of chip selects
