target system memory, the system controller writes a command code to
the monitor communications area and breaks execution of the
emulation processor from the user program into the monitor program.
The monitor program then reads the command from the
communications area and executes the 7700 Series instructions which
read the contents of the target system memory locations. After the
monitor has completed its task, execution returns to the user program.
The background monitor , resident in the emulator, offers the greatest
degree of transparency to your target system (that is, your target system
should generally be unaffected by monitor execution). However, in
some cases you may require an emulation monitor tailored to the
requirements of your system. In this case, you will need to use a
foreground monitor linked into your program modules. See the "Using
the Foreground Monitor" appendix for more information on foreground
monitors.
background
Selects the use of the background monitor. When
you select the background monitor and the current
monitor type is "foreground", you are asked the
following question.
Reset map (change of monitor type requires map reset)?
This question must be answered "yes" to change the monitor type.
foreground
Specifies that a foreground monitor will be used.
Foreground monitor programs are shipped with the
Softkey Interface. When you select a foreground
monitor, you will be asked additional questions.
Reset map (change of monitor type requires map reset)?
This question must be answered "yes" or else the foreground monitor
will not be selected.
