Functional Description and Application Information

Memory Mapping Control (S12SMMCV1)

MM912F634

Freescale Semiconductor

In single-chip modes accesses by the CPU (except for firmware commands) to any of the unimplemented areas (see Figure 44)

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).
