Escape Sequence (transparent mode)
A keyboard input consisting of a special sequence of characters,
beginning with the escape character (1C hexadecimal). This sequence
is used to access an emulator while in transparent mode. When using
multiple emulators and transparent mode to access the different
emulators, each one must be given a unique escape character.
Execution Breakpoint
A BKPT instruction placed in your software in RAM, replacing the
normal instruction at the RAM address. Breakpoints for code in ROM
are stored in emulation hardware and jammed on the emulation bus
during the fetch cycle. When the BKPT is executed, emulation
immediately transfers from execution of your target program to
execution of the emulation monitor.
Foreground
The mode in which the emulator is executing the user program. In
other words, the mode in which the emulator operates as the target
microprocessor would.
Foreground Monitor
A monitor program that executes in the foreground address space.
When the monitor exists in foreground, it is directly accessible by, and
can interact with, your target program.
Global Restart
When the same secondary branch condition is used for all terms in the
analyzer's sequencer, and secondary branches are always back to the
first term.
Guarded Memory
An address range that is to be inaccessible to the emulation processor.
The emulator will generate a break and display an error message if an
access to guarded memory occurs.
