In emulation expanded mode the external bus will be connected to the emulator and to the application. If
the ROMON bit is set, the internal FLASH provides the data. If the EROMON bit is set as well the
emulator observes all CPU internal actions, otherwise the emulator provides the data and traces all CPU
actions (see
the emulator will observe the CPU internal actions (see
