3.4 Functional Description
This section provides a complete functional description of the S12ZMMC module.
3.4.1 Global Memory Map
The S12ZMMC maps all on-chip resources into an 16MB address space, the global memory map. The
exact resource mapping is shown in
Figure 3-8 . The global address space is used by the S12ZCPU, ADC,
and the S12ZBDC module.

CPUPC[23:0]
S12ZCPU Program Counter Value — The CPUPC[23:0] stores the CPU’s program counter value at the time
the access violation occurred. CPUPC[23:0] always points to the instruction which triggered the violation. These
bits are undefined if the error code registers (MMCECn) are cleared.
