MPC566EVB User’s Manual
System Power-up and Initial Operation
RW0, RW2, RW4 – 18, RW23 – 30 provide the user access to external Reset Configuration Word
(RCW) bits not normally required for default MPC566EVB operation. The RW0 – 30 designations
reflect the data bus D0 – D30 bit affected when the RCW word is enabled externally. All RW0 –
30 option bits are defaulted to the logic low value during external RCW word operation. The user
may apply a wire jumper between the 2 pad positions of each RW0 – 30 option to provide a logic
high level on the respective bit position during external RCW operation. Note that the user could
add physical headers (2mm type) to these signals on the board. Refer to the MPC566 user manual
Reset chapter for the respective RCW bit definitions.
2.3.2 Memory Configuration (MAP_SW)
The Memory Configuration switch (MAP_SW) controls the mapping of the MPC566 chip selects
to the different external memories and whether the internal flash is enabled.I
2.4 System Power-up and Initial Operation
When all of the cables are connected to the board, power may be applied. The dBUG ROM Monitor
initializes the board and then displays a power-up message on the terminal.
