Functional Description and Application Information
In single-chip modes accesses by the CPU (except for firmware commands) to any of the unimplemented areas (see
will result in an illegal access reset (system reset). BDM accesses to the unimplemented areas are allowed but the data will be
undefined.
No misaligned word access from the BDM module will occur; these accesses are blocked in the BDM module (Refer to BDM
Block Guide).
