1.1 Processor
The microprocessor used on the MPC566EVB is the highly integrated Motorola PowerPC
MPC566 32-bit microcontroller. The MPC566 implements a PPC ISA core with 1MByte UC3F
1
flash, four UART channels, three Timing Processor Units (TPUs)
, 36 KBytes of SRAM plus
4KBytes DECRAM, 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 6KByte DPTRAM
. This processor communicates with external
devices over a 32-bit wide data bus, D[0:31]. The MPC566 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 MPC566 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.
