Chapter 18 Memory Mapping Control (S12XMMCV3)
18.4.4
The MMC controls the address buses and the data buses that interface the S12X masters (CPU, BDMand
XGATE) with the rest of the system (master buses). In addition the MMC handles all CPU read data bus
swapping operations. All internal and external resources are connected to specific target buses (see
