may erase or corrupt the debug monitor. If the debug monitor becomes corrupted and it’s operation
is desired, the firmware must be programmed into the flash by applying a development port tool
such as BDM or Nexus. User should use caution to avoid this situation. The upper 1 MByte is used
to store the MPC564EVB dBUG debugger/monitor firmware (0x0090_0000 to 0x009F_FFFF).
1.2.2 SRAM
The MPC564EVB has one 512 KByte device on the board (U2). It’s starting address is
0xFFF0_0000.
The synchronous SRAM Memory Bank is composed of one (optional 2) 128K x 32 memory
devices. These memory devices are connected in linear order from U2 to U3 if more than one is
available, so that the low order address of the memory bank will access U2 and the high order
addresses of the memory bank will access U3. This memory bank must be configured as a 32 bit
wide port but is byte, half word, and word accessible for read or write operations.
Also see Section 1.2.5, “MPC564EVB Memory Map”.
1.2.3 Internal SRAM
The MPC564 processor has 32-KBtyes of internal memory which may be used as data or
instruction memory. This memory is mapped to 0x003F_8000 and configured as data space but is
not used by the dBUG monitor except during system initialization. After system initialization is
complete, the internal memory is available to the user. The memory is relocatable to any 32-KByte
boundary.
1.2.4 Internal Flash
The MPC564 has a U-bus CDR3 flash EEPROM module (UC3F). The primary function of the
UC3F flash EEPROM module is to serve as electrically programmable and erasable non-volitle
memory (NVM) to store program instructions and/or data. The MPC564 flash EEPROM array has
512 Kbytes of NVM that is divided into eight 64-Kbyte array blocks. If the flash array is disabled
in the IMMR register (FLEN=0), then neither the UC3F array or the UC3F control registers are
accessible. This feature allows the MPC564 to emulate the MPC561/562.
Please refer to the MPC564 User’s Manual for more details.
1.2.5 MPC564EVB Memory Map
Interface signals to support interface to external memory and peripheral devices are generated by
the memory controller. It supports four regions on four chip-select pins. The general purpose
chip-selects are available on lines CS[0] through CS[3]. CS[0] also functions as the global (boot)
chip-select for booting out of external flash.
The internal flash can not be programmed at 66MHz. Please see the
MPC564CZP66 Electrical Spec for other limitations at 66MHz.
