1.1 Processor

The microprocessor used on the MPC564EVB is the highly integrated Motorola PowerPC

MPC564 32-bit microcontroller. The MPC564 implements a PPC ISA core with 512KByte UC3F

flash, two UART channels, two Timing Processor Units (TPUs)

, 32 KBytes of SRAM, a QSPI

(Queued Serial Peripheral Interface) module, three TouCAN modules

, 12 PWMs and 6 counter

submodules in the MIOS, enhanced QADC64E, PPM module

, a Nexus debug interface port, and

8KByte DPTRAM

. This processor communicates with external devices over a 32-bit wide data

bus, D[0:31]. The MPC564 can address a 32 bit address range. Only 24 bits are available on the

bus however. There are internally generated chip selects to allow the full 32 bit address range to be

selected. There are regions that can be decoded to allow superviser, user, instruction, and data each

to have the 32-bit address range. All the processor’s signals are available through the expansion

connector (BUS_PORT). Refer to the schematic for their pin assignments.

The MPC564 processor has the capability to support both an IEEE-ISTO 5001-1999 NEXUS port

and a BDM debug port. These ports are multiplexed and can be used with third party tools to allow

the user to download code to the board. The board is configured to boot up in the normal/BDM

mode of operation. The BDM signals are available at the port labeled BDM_PORT. The NEXUS

connector is near the reset switches on the board. It is the 2002 50 pin standard I/O connections and

connector. The BDM and NEXUS ports can not be used at the same time.

The MPC533/4 has limited or no functionality for this module. See Appendix A.
