Chapter 17 Memory Mapping Control (S12XMMCV2)
17.5.3
The MCU offers two modes to support emulation. In the first mode (called generator) the emulator
provides the data instead of the internal FLASH and traces the CPU actions. In the other mode (called
observer) the internal FLASH provides the data and all internal actions are made visible to the emulator.
17.5.3.1
In single-chip modes the MCU has no external bus. All memory accesses and program fetches are internal
(see
17.5.3.2
In emulation single-chip mode the external bus is connected to the emulator. If the EROMON bit is set,
the internal FLASH provides the data and the emulator can observe all internal CPU actions on the external
bus. If the EROMON bit is cleared, the emulator provides the data (generator) and traces the all CPU
actions (see
