System Memory

Since the MPC564 chip selects are fully programmable, the memory banks can be located at any

location in the MPC5xx memory space.

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 MPC564 is detailed further in the

MPC561/3 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

MPC564 Internal Flash N/A MAP_SW. 8, may effect mem-

ory map of chip selects

1.2.5.1 Memory Device / Bank Selection and Configuration.

The MPC564EVB board has two internal memory banks, two external memory banks and a

Peripheral memory bank that provide:
